Chicago-Latrobe 41624 135° Jobber Drill Bit
This Chicago-Latrobe 41624 jobber-length drill bit measures .3750 in diameter with a 135-degree split point. It is made from high-speed steel with a TiN coating for general-purpose drilling in metal and other materials. The tool suits machinists and maintenance technicians who need a standard fractional-size bit for everyday use.
Check shank fit and machine capacity before ordering
Verify that your drill chuck or collet accepts a straight shank of this diameter. Ensure the spindle speed range matches high-speed steel cutting parameters for the workpiece material. Confirm the jobber length provides enough reach without exceeding the machine’s throat depth or workpiece clearance.
Sustained load performance with TiN coating
The TiN coating reduces friction and heat buildup during extended drilling cycles compared with uncoated high-speed steel. The 135-degree split point maintains centering and chip evacuation as the cutting edges wear. Consistent feed pressure and proper coolant use preserve the coating integrity over long production runs.

How does the 135° split point affect drilling in a hand-held drill?
The 135-degree split point reduces walking and lowers thrust force, giving cleaner holes in steel with a portable drill.
