DeWalt Extreme 2 Drill bit

[Neil]

Got fed up with using a lip and spur and having repeatedly to keep stopping to clear it despite withdrawing the drill bit every five mill so went out and bought three 7mm dewalt extreme 2 drill bits at 2.79 each from screwfix. Fantastic, solved that problem and because its not as long as the 7mm colt thats been sidelined as well.
Thanks to whoever it was who mentioned the dewalt extreme drill bit last week.

It was Peter (penpal) if memory serves. I use them too - no complaints!

I have no engineering knowledge and must admit I don’t know what a lip & spur drill that Neil used is. However I asked my daughter for two Colt pen drills ( 25/64 & 15/32) for the baron pens. I want to start drilling and don’t stop until the drill comes out the other end without any break out of the blank, thus the request for the Colt drills as a Xmas present.
She gave me a Colt 25/64” but a Fisch 15/32” and I didn’t know how the Fisch would perform. Today I drilled two barons, an olive wood and an acrylic blank. Both drilled at 2000 revs and both went straight through without stopping and no break out. I know they are expensive but without any understanding of drills and how they work I want a one stop shop and these appear to be it.

Do you mean these Neil??
Been using em for ages init?
There have been many discussions on them in the past Walter was an advocate of them I think.
I have to admit the carry case they are in is firmly attached to my pillar drill these days so they are never far away from where needed.
Although I still use any old drill on the lathe as long as I keep it sharp init?

Not exactly, right drill, wrong volume, I just bought the 7mm on its tod, didnt need the other metric drills.

I wasnt in the market for a drill bit probably when it was previously being discussed so didnt pay too much attention at the time.

Looks the same to me but hey ho.
Give me your phone number so we can arrange a meet. I have tomorrow afternoon free.

Neil, young Matty's Father on this forum gave me three 6.9mm Dewalt drill bits recently, and agree they do the business.. I just bought five 6.9mm HSS Drill Bits from Axminster, it is surprising what a difference that 0.1mm does to reduce the gap between blank and tube ...

Maurice, i don't have a bad word about the Colt drills, especially when using them with Acrylic ...

 

[Penpal]

The only caution is drilling laminated material with the DeWalt drills they simply build up mon the drill point and skid but my recent review of these drills was based on real pleasant experience using them.

Kind regards Peter.

 

[Neil]

I don't like using the colt 7mm nor 8mm as they are too long for the width of the drill, are not strong enough and skid on the surface of dense material.

Interesting reading this as I have a set of DeWalt Extreme drill bits that I could never get on with as I found they gave too aggressive a cut, in some cases pulling themselves out of the chuck.
This was when drilling in side grain, I will have to give them another go as I imagine the same won't be true when drilling end grain wood or acrylics.

Doug, interesting, I guess the dewalt drills were never designed to be used as a tail stock drill and used at relatively low speeds. I drill at medium pillar drill speeds whatever they are, not in workshop at the moment. I guess that if you are drilling into a piece of end grain rosewood the drill will almost want to tap the wood as opposed to drill it?

This is very interesting. I broke my colt 6.9 which I thought was perfect for 7mm tube a while ago and have been using 7mm. I also think its too long for the width of the drill but have persevered through laziness in getting another. This thread has spurred me into going to screwfix to try the DeWalt which might just be a tighter 7mm hole than my current one. Failing that, its Axminster for the 6.9mm.

 

[Penpal]

Personal preference is for 7mm and polyglue gives room for a tight press to expand the brass not split the timber etc. Speed never changed for pens ever or type of drill one of the touchy feely things for me has been kind to me when any drill has grabbed at reentry it has been too slow speed always never too fast. I use excess glue consider it a cheap part of the process. Bought the first DeWalt type 2 drills when only singles were sold I used the larger sizes with huge success drilling before tapping steel pipe especially when I was up high building a large frame from 6 inch 3/8 inch wall thickness that drill point never tracked for my safety in retrospect one of my best purchases, initially I rang America and the manufacturer said the Type 2 drills were developed for stainless steel and E Mailed me the full specs. I believe firmly the best drill is the one that fits your needs, methods and experience like motor cars and many special things we all have our predudices likes and dislikes.

The major dissapointment that came to me once was to give a ringing recommendation to a boss a friend on behalf of a worker a friend both famous for overall compatability, they fought like Kilkenny cats never did overcome it. I understand like one of the new purchasers of a DeWalt the revelation not having paid heed to my rumblings in a post proving to me detailed dissertations on deep technical matters are irrelevant to others until people try for themselves.

Interesting this world is very small in manufacturers and purchasing.

Kind regards Peter.
