Chicago-Latrobe 27/64" Jobber Drill Bit

This Chicago-Latrobe jobber drill bit measures 27/64 inch with a decimal equivalent of .4219. It is made from high-speed steel and features a bright, uncoated finish. The 135-degree split point helps the bit start on contact and reduces walking during use. It suits general-purpose drilling in metal, wood and plastic where a standard fractional size is required.

Capacity and headroom for fractional drilling

The bit handles holes up to its 27/64 inch diameter in materials suited to high-speed steel. It runs out when the application demands a coated or carbide tool for extended life in abrasive or high-heat conditions. The uncoated surface limits wear resistance compared with treated alternatives. Buyers who need coolant-through capability or a different point geometry should select another design.

Questions about this item

Will the 27/64 inch split-point bit start cleanly in my older drill press without a centre punch?

The 135-degree split point is self-centring, so it bites immediately on contact and reduces the need for a centre punch even on a worn chuck.

How can I confirm the 41027 bit is cutting correctly after the first hole?

Check that the chips are tight, golden spirals and the hole measures .4219 inch; rough chips or a loose fit mean the speed or feed needs adjustment.
