Chicago-Latrobe 54061 Cobalt Jobber Bit
This Chicago-Latrobe 54061 is a 19/64 inch cobalt jobber length drill bit built for heavy-duty drilling tasks. The 135 degree split point reduces walking and allows faster penetration into hard materials. It suits professional mechanics and maintenance technicians who need reliable performance on tough alloys. The TiN coating adds surface hardness and extends cutting life.
Check shank fit and material compatibility
Verify that your drill chuck accepts a straight shank of this fractional diameter before ordering. The bit is designed for non-coolant through applications and has zero coolant holes, so external lubrication is required for deep cuts. Ensure the workpiece material matches cobalt cutting geometry for best results. Confirm the decimal equivalent .2969 matches your hole specification.
Cobalt construction with TiN coating for durability
The HAWA cobalt alloy resists heat and wear when drilling stainless steel and other high-tensile alloys. TiN coating lowers friction and helps eject chips during continuous use. The 135 degree split point is self-centering, reducing the need for centre punching on flat surfaces. Jobber length provides standard reach for general workshop drilling depth.

Questions about this item
Does the 19/64 in cobalt jobber drill bit come as a single piece or in a set?
The 54061 is supplied as one 19/64 in cobalt jobber drill bit with a 135 degree split point and TiN coating; no additional bits or accessories are included.
When should I choose the 19/64 in size over another fractional diameter?
Select the 19/64 in bit when the job calls for a .2969 decimal equivalent hole; other fractional sizes are offered separately for different diameters.
How does the 135 degree split point affect drilling in a hand-held drill?
The 135 degree split point on the cobalt bit reduces walking and starts the hole cleanly without a centre punch, even in hard metal.
