Chicago-Latrobe 42018 Drill Bit

The Chicago-Latrobe 42018 is a jobber length drill bit sized at 9/32 in with a 135 degree split point. It is made from high speed steel with a TiCN coating for extended tool life. This accessory targets professional machinists and maintenance technicians who need reliable holemaking in metal.

Suited for metal drilling tasks requiring

The split point geometry allows the bit to start on contact without a centre punch, reducing walk on hard surfaces. It suits workshops producing repeatable holes in steel or alloy. Buyers who need coolant-through capability or a different point angle for specialised materials should look at other options.

135 degree split point geometry

The 135 degree split point is the specification that determines suitability for hard metal drilling without walking. The decimal equivalent of .2813 in confirms the exact size for toolholder compatibility. Match this point angle and diameter to your application requirements before purchase.

Questions about this item

Does the 135° split point on the 42018 drill bit reduce heat buildup during extended drilling?

The 135° split point design centres the bit quickly and reduces thrust, which lowers friction and heat generation during prolonged use.

What shank size must my drill chuck accept to use the 9/32 in jobber bit?

The bit has a standard jobber shank matching its 9/32 in (0.2813) diameter, so a chuck capacity of at least 9/32 in is required.

Will the TiCN coating on this 42018 bit wear prematurely when drilling older mild steel workpieces?

The TiCN coating increases surface hardness and wear resistance, extending bit life even in older mild steel applications.
