Machining Steering Columns

[bill-e-boy]

I was attempting to drill the column turn and shift levers but it all went pear shaped. Back to square one unfortunately

I need to invest in some PCB drill bits to do this as suggested by Daniel above - the search is on

PC Board drill bits are made from Tungsten Carbide (extremely hard and drill effortlessly through almost anything), have split point, and 1/8" shaft.  I use them almost  exclusively. They made my drilling tasks much easier.

While new ones are very expensive, there are sources of either much more affordable used (with plenty of life still left) or resharpened PCB bits.

Bill-E-Boy credited me with making wheel hoops. Not me I am afraid. You need to credit the Bill Newcomer who's post preceded mine.

PCB board drilling bits. As mentioned they are made from Tungsten Carbide and extremely brittle. The smaller diameters break very easily when subjected to any sideways stress and needs a flat surface to drill into, whether the end of a bar in a lathe or a piece of material sheet or block. Presenting anything flat at an angle or something with a radius to one of these bits is asking for a breakage.
