Hertel 04141016 Cobalt Jobber Drill Bit 5/32 Inch

Product Description

The HERTEL 04141016 is a cobalt jobber-length drill bit with a titanium nitride (TiN) coating, designed for heavy-duty holemaking in hard and abrasive materials. It measures 5/32 inch (0.1562 inch decimal) in diameter with a 3-1/8 inch overall length and a 2-inch flute length. The 135-degree split point reduces walking on entry and requires no center punch on most surfaces. The web-thinned, tapered web construction lowers thrust requirements and improves chip evacuation. This bit is suited for machinists, fabricators, maintenance technicians, and trade professionals who drill through hardened steels, stainless, and tough alloys where standard high-speed steel bits wear prematurely.

This jobber drill is sized for general-purpose holemaking across metal fabrication, HVAC equipment manufacturing, structural work, and maintenance and repair operations. The straight-cylindrical shank seats in standard drill chucks and machine spindles without modification. The regular spiral flute geometry and right-hand cutting direction make it compatible with conventional drill presses, CNC machining centers, and handheld power drills. It is particularly well suited for applications where hole quality and bit longevity matter more than initial tooling cost.

Key Features

• Cobalt construction with TiN coating for extended tool life in hard and abrasive materials
• 135-degree split point reduces drill walk and lowers entry thrust
• Web-thinned tapered web improves chip flow and reduces heat buildup
• Right-hand spiral flute geometry compatible with standard drill equipment
• Straight-cylindrical shank fits conventional 3-jaw and collet-style chucks
• Heavy-duty grade construction rated for demanding production and field use

Compatibility

Designed as an OEM-style jobber drill for use in standard drill chucks, drill presses, and CNC machining centers accepting a 5/32 inch straight-cylindrical shank; fits within the 0.1500 to 0.2000 inch decimal drill size range.

Installation Notes

Secure the shank fully in the chuck and verify runout before drilling. Power down and de-energize any machine tool before changing bits. Use appropriate cutting fluid or lubricant when drilling ferrous metals to reduce heat and extend coating life. Coolant-through operation is not supported on this bit.
