Thread: Ever seen this "Drill Pad" as described by Workshop Practice Series?
18/12/2018 17:56:41

I’m a bit surprised that these things exist as a bench drill is very often the first machine tool that folks buy. smiley

Some may find this of interest.

Carbon steel make good finishing scrapers for woodturning if you can find them.

Thread: 2.05mm or #45?
15/12/2018 18:39:16

I’ve ordered the Workshop Practice book.

The drill bits arrived today. I wouldn’t normally measure them but I did today just for you guys. laugh they were:

2.05 1

2.06 2

2.07 4

2.075 1

2.08 2

So any of them will do. I measured one of them with a M&W mic and also with a Mitutyo so I’m reasonably confident of shank size. How well they’re sharpened is another matter but I’m sure they’ll be fine.

Thread: Drill Speed

Well that’s what I though Brian, 1000 rpm for a 1” twist drill in Alloy, I’d be nervous at half that.

15/12/2018 16:10:11

ega, Yes, I’ve found the Bullet drills to be very good, I’ve even used them as makeshift counterbores. Several companies including Black & Decker and DeWalt sell them.

What’s the general consensus on this chart?

Do some of the speeds look a bit too fast for hobbyist equipment? face 7

Thread: Blackening steel parts

You weren’t the only one Michael, several others on another forum thought it was a computer generated image.

I’ve used Gun Blue many times and it works very well on small parts giving a very deep black. I find heating the parts a little and them immersing them in the liquid works best. An oil coating afterwards helps protect the surface. Bigger parts are not so easy unless you can afford to buy a gallon of the liquid (it’s not cheap). What I’ve found is that the surface finish hugely effects the blacking process. I’ve personally found shiny or polished parts are much more difficult to black than sand blasted parts. In fact I seldom seem to black parts these days, I just sand blast them then wipe them over with Microcrytalline Wax. Have a look at the pictures of the tool holder in my album. At least one person thought it was a computer generated image.

I have some HSS toolbits that say 5% or 8% cobalt. If this is what you have it’s just one of many grades of HSS that are available.

I recently bought an M42 HSS wood turning gouge as it was supposed to be a lot better in terms of sharpness and longevity of the edge but I can’t see it’s any better so far.

Here’s a PDF you can download Ron.

I seem to have had various carbide insert charts over the years but I always seem to lose them. sad

Beware any ANSI insert data, these are American. I think most of the planet use ISO. Anyone confirm?

Thread: Optical Centre Punch any good?

Here’s the start of a four part video on making one. Make sure to look at the other three.

Thanks Jason, do any of the numbers relate to the letters or are they just a part number, mine is CCMT060204

The numbers relate to size, in your case Ron from left to right it’s cutting length, thickness then tip radius.

No doubt it will differ from drill to drill but I have the impression that with these smaller sizes, if you first use a drill 0.1 mm undersize and than finish with the size you actually want, it gives you a hole diameter closer to the nominal. Niko.

Yes that makes sense. I’ve not had any problems though with the 2.05mm drill I’d been using until I snapped it! laugh

+ For UK Drills,Bought many drills from them.

Good prices,good service,and no silly delivery costs !

What more could you want ?

Same here but they don’t list a 2.05 drill that I could find on their website, and certainly not on eBay where they do free postage.

There was an article in MEW showing how to make your own for those so inclined. We had a bought one at work and it was very good.

Thread: 2.05mm or #45?
13/12/2018 14:43:18

I was aware of the percentage engagement idea but generally stick with the normal recommendation. Thanks for that though Eric, I think that’s a good idea. I’ll take a look. yes

13/12/2018 13:40:30

That’s what I was hoping Brian, thanks. yes

The bits are ground Cobalt HSS from RDG so I’m hoping they’re reasonably sized. To be honest though I’ve measured top brand drill bits with a micrometer before and they often differ a little from the size marked for some reason.

13/12/2018 12:19:10

I tried to buy a pack of 2.05mm drill bits on eBay as I snapped my second to last one the other day. I only got a couple of hits and they were silly money like £8 each plus postage from Germany. I double checked the required tapping drill for an M2.5 thread and I actually got two answers online - 2.05mm and #45 which appears to be 2.0828mm. I searched eBay for #45 drill bits and got lots more hits so I bought a pack of 10 #45 for about a fiver inc postage. Which is right though and will it make much difference?

Yes Ian, the polished Carbide are sharp. I like using them on alloy as well. The round ones are popular in hollowing tools for wood turning.

Ron, good question but I don’t know the answer!

10/12/2018 17:19:12

I’m less concerned about size, than the cutting tip of the insert itself. Although brand new they appear quite blunt.
