- Sharpen a right hand 2 flute high speed steel drill with the Brierley grinder.
I had an older ZB21 machine and struggled with the manufacturers instructions which referred to locks and pins which were not on that machine.
Once I had this ZB32 I could see how it worked and could translate that to the older unit (after making a missing part). Other Brierley grinders will have the setting locks and stops arranged differently but the functional movements will likely be the same as this one.
Thanks for the video I just bought a z25 and this has helped very much in understanding how to use it correctly. and being a man from cheshire its great to see a uk based teacher putting this out there. regards Jeff
I'm thrilled to find such detailed technical content on RUclips.
Thank you!
Just bought same machine glade you made this video. I am still struggling a bit with it .Guess it takes time to learn
Brilliant video!!! thank you very much, i just got a ZB25 and although i have an instruction manual, your video has made the setup a whole lot clearer!
It is possible to send the operating manual in PDF
@@ragabhanfy506 if i get time i shall, but im very busy right now, give me a few days or so
Thanks for the video, greatly appreciated. I also have the instruction manual for mine but this makes it far easier to understand. Once again, thanks.
Thank you very much for the video. Perfectly sequenced and edited. It takes a lot to learn all the aspects of the machine and then work around the camera to convey all of the proper information as well as you did here. As a person that learns much better by watching a video rather than reading a manual I truly appreciate your thoughtfulness in sharing the information. I will be watching the other videos on your channel particularly the ones about the drill grinder. I just purchased the ZB25 model secondhand and will definitely be benefiting from your instruction.
I was a Machinist in the US Air Force. Stationed at Grand Forks AFB ND. The Motor Pool had a Brierley Drill Bit Grinder that they did not use. For a short time I was acting Shop Chief after our Shop Chief got drunk and went AWOL The Motor Pool needed a couple of flywheels turned on the lathe. Being the Aircraft Machine Shop the vehicle's were not our reasonability.
I offered to swap machine work for the Brierley, the Motor Pool was fine with transferring ownership to us as the grinder was just colleting dust.
I played with the drill grinder but never really used the machine. I had gained the skill to sharpen bits by hand and for me it was quicker.
Proper engineering skills, hats off to you. Grandad could do the same , minimal kit, great results. Very handy with a file and a hammer too ... one arm like popeye. Appreciate the comment.
Thanks for your wonderful video, Mine is missing the drill gauge holder The round thingamabob that the gauge slides in, but seeing yours I will have a go at making one, I jerry rigged a sliding unit but prefer yours as original is usually best. I have used mine for some interesting things over the years, will do a video to show them someday. Keep uploading!
Bjr c'est une très Bonne machine elle présente beaucoup d'autres possibilités à exploiter.
This is such a good video!
Thanks for the video!
You're a great " " 'splainer"! Thank you! "Where can I get a machine like that and how much does it cost"...........he sheepishly asked. ;-)
hi there
I sold a tidy ZB25 on Ebay for £510 with plane wheel ,dish wheel , correct drill setting post, 6 cams ,hub wrench, spindle lock, MT1 steady, drill centring tool and manual - which is enough to get you away and grinding.
I reckon for a bigger ZB32 on a cabinet in good nick as above (MT1/MT2 steady) around £1500 ..... expect to collect in person . Make sure the machine is original without shop made replacement bits. Look at a picture of inside the cabinet as unlisted extras may be hiding there.
If it comes from a dealer with all original spec and in good nick £2100.
Machines with all the buzzers and whistles don't come up too often. Mine came as you can see plus the dust extraction unit for £2500 from a dealer who mainly sold big CNC stuff so his regular clients weren't interested and it had been sitting around a fair bit.
There are other proper drill out there which look equally as good, the main thing is the machine is in original manufacturers condition .... so wait for a good one . Check completed items listings to gauge current market values
All best

@@shedmade3264 Thank you!
@@shedmade3264 I just picked up a ZB32, with assortment of parts. It’s filthy as it came from a foundry. Where I wipe the dust away, it looks great, plus chuck has no score marks from being in contact with wheels. It came with a load of stuff, cams, taper holders, drill gauge etc, but trying to work out which of the accessories relate to the grinder. There’s a U shaped piece of rod, with ends bent up, almost like a tool for undoing the central hub, but it’s too big; plus in addition to the spring loaded dresser, there’s another one, bigger in size to the end of the dresser tool - wondering if these are part of the accessories for it? Grinder motor is single phase 110 or 220 volts which is great!
@@Rafal-Pisula
sounds like you have a nice machine.
Mine came with a box of random stuff which does not appear in the users manual and I couldn't work out what it was for - so I kept it all just in case it comes in handy one day.
happy grinding

✈Thanks for the video, greatly appreciated. Once again, thanks.
This is such a good video!
Great informative video!
ῳ💡❀ Very Good my love ∰§
Hi. You have the best video for explaining . Is a coefficient to multiple for metric drills ? I have a similar grinder, but I didint understand how much I need to pull the drill out. In am metric and I don’t have the blade in the front numbered. Probably another producer because is bigger to .
Это тот самый случай когда наше авось не работает, всё технически предусмотренно а именно: угол заточки вершины сверла, конусный или цилиндрический хвостовик, угол наклона задней кромки отвода стружки от режущей кромки, длина самого сверла и что весьма вероятно правка затачиваемого диска алмазным бруском. А всё это видно оправдывает расходы покупки такого станка, когда работает целый цех станков с ЦПУ и требуется хотя-бы раз в смену замена свёрл, на уже доведённые до кондиции.
good tools
@shedmade. Do you by chance have the dimensions of the cams? I have a machine with no cams so plan on making them.
Great informative video!
Can this grinder be used to sharpen endmills?
It can sharpen 4 flute tap and core drills with the correct cam - no mention of end mills. So I guess not
If anyone knows better please comment.
All the best Shed guy
فيديو ممتاز شكرا
I am currently re-commissioning a ZB32 which I have had for many years and your video has given me a better understanding of the machine. As you state, there appears to be many variations of these machines. The manual I have is type written and is different in many ways from the actual machine.
Do you use the grades of wheel recommended by Brierley, or something different?
Do find balancing really necessary. Someone once told me that modern abrasive wheels are much more uniform in structure such that balancing is not as critical these days. I don't have a balancing stand and arbor for my machine so I may run into problems if balancing is an issue.
I stuck with the recommended wheels from Brierley, and the best finish I managed was with Norton white aluminium oxide wheels.
Make sure a wheel rings true - tap it to see if it is cracked as a starter for 10. If the machine is smooth as silk running without a stone, and then vibrates when a stone is on then there is a problem with the balance. Try dressing it. I am not convinced with the plastic snap in arbour adapters and prefer to make a bushing.
On my ZB 32 the arbour mount has adjustable balance weights on capheads. These will need to be evenly spaced . Have a look on youtube university - wheel information will be common to many grinders
All the best
@@shedmade3264 If you don't mind mew asking, where did you buy your wheels from. Also, were they off-the-shelf, or recessed to your requirements?
@@glynbrandon861
Glyn
they are off the shelf items I think from MSC, they have a reasonable range without having so many that you get boggled by it.
having said that the I am sure that specialist firms would be able to give guidance
good luck

Is this machine for sale
As Ant and Wayne have mentioned, You video fills in the missing bits that perhaps I'm to stupid to understand from the manual.
I am missing the setting gauge on my machine, But with a bit of trial and I can get the tip looking correct.
If anyone has a setting gauge for sale or dimensions of one please let me know.
Does anyone have any idea why the relief detention keeps jumping down the scale when I am grinding ? Thanks
hi
that's blooming annoying
Mine has a spring loaded ball detent which locates and holds the correct position. Check to see if it is gummed up , to the spring has given up the ghost
good luck

Nice Video. Your grinding wheel is smeared. Drill is getting blue. How old is this maschine? Im Shop i use german "Klingel" and "SWU" from GDR.
yep spot on . I just dressed it with a diamond dresser and it is way better - many thanks
I guess the machine is from the eighties - so pretty much the newest thing that I have.
the german machines look superb, serious kit. the klingel site is very informative, and I guess the support is there . information on the brierley is harder to come by.
i could have driven 10 miles to the hardware stor and got back drilled the hole before you go it sharpened lol
Hi I Want Cams
Go buy a drill doctor its verry easy to use and does a perfect job every time this thing is bull
Not so.
This unit will sharpen up to 32mm drills, (inch and a quarter), sharpen centre drills, pilot drills , multistep drills, cut all point angles, sharpen 4 flute drills and taps, produce Truax spiral point geometries, grind radial relief , grind subland drills ..... oh and also grind left hand drills.
Its not for everyone, but its a real piece of kit ..... credit where it is due
@@shedmade3264 I'm sure it's a good tool but for a fraction of the price a drill doctor will do most any drill a home owner would have. I sharpen all mine by hand have been for over 20 years so I'm pretty good at it now and dont need either.
thanks for the video I know someone has got alot of good useful information
@@luappaul7240 Surely you're just trolling right? Of course a drill doctor might be a good value to a DIYer or homeowner for occasionally touching up standard drills in standard sizes but this machine is obviously not designed or marketed toward homegamers in any way.
@@micahned in a way yes but look out there now days people dont have enough brain power to operate a can opener they will never figure this out lol
@@luappaul7240 drill doctor is idiots, serious hobby engineers won't buy that shopping channel crap
I just wanted a sharp drill bit, not fly a jet aircraft
