From Holes to Slots

[Geoff's Project]

Is there a tool that I can use in an electric drill which will allow me to elongate a hole to a slot,

Yes I have drilled some holes not quite in the correct location, slotting them is not a problem, I'm just looking for the right tool to do the job instead of using a file.

I used a 240 volt Dremmel. Dremel - Big on detail

reamers allow you to drag holes as well. Or chain drill the hole and file in between.

Tungsten carbide burrs spun with a dremel will cut through steel like hot butter cuts through a knife! The shavings that come off are like needles and are quite nasty!

if you use any of the methods above, clamp a piece of wood onto the job as a guide for the tool, otherwise it will wander and look a mess.

on fibreglass, a dremel fitted with a tile cutting bit works a treat

I have a dremel great bit of kit but burnt it out enlarging a hole in ss
took it back to tool merchants and the dremel guys replaced it cant complain about that .then i purchased one of those wolf craft Felix drives that fits into a drill chuck .
I find this has more power and more pen like to get into those tricky spaces

A handy tool is a Bosch multitool (all rounder) you can get a cheap corded one about £65 or a cordless. It has a flat spatular type blade you can just plunge straight into wood / fiberglass etc.

Will plunge cut straight into a solid surface, imaging getting a wallpaper scraper and being able to just push it into a solid surface.

Then you can drill two holes one at each end of the slot and plunge cut top and bottom to give you a perfectly straight slot.

May not be the correct tool but its one of them tools that you will get out now and then and think wow thats just what I wanted.

I use mine to sink in plug boxes / trim door bottoms / rip up flooring without damaging the planks all sorts of stuff.

You can make a flush cut on top of a surface without marking the worktop that sort of thing, lots of adapters for it to do most things.

There is a tool that you can fit to an electric drill and it nibbles at the steel so that you can produce any shape of hole or slot that you want! cannot find it but you see it at some of the shows
