Drill Bits

[mike gowland]

Fixing the body to my Dax chassis this weekend.:thumb:

Started drilling the chassis rails however my drill bits seem to last one per hole before they become totally usless. Seems that B & Q's finest are not up to it!

Can anybody recommend drill bits that are up to the task?

Not meaning to tell you how to cook eggs :angel: but if you have the drill on too high a speed and it starts to get too hot this will blunt any drill no matter what make or how much you spend on it . You need the drill on the slower of 2 speeds if it has 2 speeds, don't apply too much force and just take your time, stopping immediately if it starts to get too hot.

Dont underestimate my lack of ability!

Now, tell me about the eggs!

what size holes are we talking? a pilot hole through first may help you

[mike gowland]

5/16 the full size.

pilot holes were no problem.

As said. Slower Speed BUT, keep a resonable pressure on so that it keeps cutting. Lower pressure will let the drill bit slip which will A) Make it overheat, which will B) Workharden whatever you are drilling, Which will C) Blunt the Drill

Sometimes pilot holes can be the killer, the drill bits in too hard and gags on the swarf, so you back opff and then it just tries to polish if the cutting edge.

Tinks.
I drill all the holes with an air drill and these things drill at least as fast if not much faster than any electric drill without problems, this is not to say that my staff are as sucessfull with drill bits, they don't have to pay for them.

Try to get hold of Dormer drill bits, these are much better than the plastercine ones that are available from B&Q


A good tip:-
If the drill bit starts to squeak then stop drilling straight away. This is happening because the cutting edge has now gone and two pieces of flat metal are rubbing against each other (Drill bit and work piece), All that will happen if you keep drilling is that you will turn the drill bit into a metal cotton bud that will be so soft it will never drill again even if sharpened.:thumb:

Lube the bits while drilling, WD40 works ok. Lube helps to cut and cool. :thumb:

How about this?
THIS IS BEST IF READ OUT LOUD

Rindercella and her sugly isters lived in a marge lansion. Rindercella worked very hard - frubbing scloors, emptying poss pits, and shivelling shot. At the end of the day she was nucking fackered. The sugly isters were right bugly astards. One was called Mary Hinge, and the other was called Betty Swollocks. They were really forrible huckers, and had fetty sweet and fetty swannies.

The sugly isters had tickets to go to the ball, but the cotton runts wouldn't let Rindercella go. Suddenly there was a bucking fang and her gairy fodmother appeared. Her name was Shairy Hithole, and she was a light rucking fesbian. She turned a pumpkin and six mite whice into a hucking cuge farriage with six dandy ronkeys who had buge hollocks and dig bicks.

The gairy fodmother told Rindercella to be back by dimnight otherwise there would be a cucking falamity. At the ball Rindercella was dancing with the prandsome hince when suddenly the clock struck twelve. "Miste all chucking frighty!" said Rindercella, and she ran out tripping b4se over ollocks, so dropping her slass glipper.

Next day the prandsome hince knocked on Rindercella's door and the sugly isters let him in. Suddenly Betty Swollocks lifted her leg and let off a fig bart. "Who's fust jarted?" asked the prandsome hince. "Blame that fugly ucker over there" said Mary Hinge. When the stinking brown cloud had lifted, the prandsome hince tried the slass glipper on both the sugly isters without success. Their feet stucking funk.

Betty Swollocks was ducking fisgusted and gave the prandsome hince a nack in the kickers. This was not difficult as he had bucking fuge halls and a hig bard on. He tried the slass glipper on Rindercella and it fitted pucking ferfectly. Rindercella and the prandsome hince were married. The hince lived his life in lucking fuxury, and Rindercella lived hers with a follen swanny.

And they all lived happily ever after.
