fitting rim latches

[horsefeathers]

Just wondered....

when drilling the 32mm hole in a door ready for fitting a rim cylinder, do you prefer to use:-

A) 32mm flat wood bit?
B) 32mm holesaw?
C) Woody Woodpecker?
D) the power of hole-fu?
D) something else?

Answers on a postcard please, or post your answer here for quickness!

For those show offs whose attention to detail borders on insanity i thought i would get in first!!

preferred tool is a 32mm holesaw

I use a 32mm spade bit but i put masking tape on the side i start to stop any splinters then once its piereced other side i do the same on that side. Hole saws i find bit more awkward so stopped using it just in case it jumps and slips

i prefer to use a holesaw

[AJS]

I prefer the holesaw due to the nice clean hole that is left as oppposed to the spade bit which I find can create an oval hole if you are not carefull to keep it straight and true. At the end of the day it is down to personal choice.

I use flat bit which usually is ok for me. But yesterday ran into a door where there was solid wood in the first inch or so of the door edge, then weak chipboard material for the remainder. So of course my flat bit didnt run true as it wanted to take the path of least resistance, ie veer towards the chipboard. Luckily the slightly oval hole was hidden behind the cylinder ring.

So I assume in this instance a holesaw would have been better!

i use an auger bit i find them a lot better

Auger, nice true line and a habit left over from being taught to fit with a brace and bit. Watch the tip pierce through and then swap sides to avoid any wood splitting.

ive only ever used a hole saw, but woudl like to have a blast with speed bit, an auger see wich i like best..

also hear in australia ( i assume its the same every where else) but alot of the new doors have fire ratings and you wouldent be able to drill through them with a spade bit because of the materials in them

I used to use a hole saw with the drill mounted in a drill jig which I clamp to the door. A hole saw can go off line very easilly if you're not careful.
One of the problems I encountered with the holesaw was with burning wood and clogging teeth, slowing the drill solved the first but the second meant that it required withdrawing the bit and cleaning the teeth a couple of times, plus the fine dust that it creates made me cough for hours afterwards. I now know that some exotic hardwoods are toxic if exposed to them for any period of time.

Recently I have started to use a MAD bit (Multi Angle Drill) which don't seem to mind what type of material you are drilling into, produce larger swarf like a spade bit, don't burn the wood and, unlike a Forstner bit, they don't clog in the bore.

I still mount my drill in a jig but now I get a perfect 32mm hole that is as straight as an arrow every time. Individual 32mm bits are £10.99 each from a well know supplier, haven't seen them any cheaper but let me know if you do.
