Hertel 2386274 Drill Bit Size 20 Hss 135 Degree Split Point

Product Description

The HERTEL 2386274 is a screw machine length drill bit designed for high-speed, precision drilling in metal fabrication, machining, and general manufacturing applications. Built from high-speed steel with an oxide coating, this bit carries a wire size 20 designation with a decimal diameter of 0.1610 inches and an overall length of 2.125 inches. The 135-degree split point reduces walking on entry and lowers the thrust force required to start a hole, making it well-suited for production environments and CNC or manual drill press work. The web-thinned, parallel-web construction improves chip evacuation and reduces heat buildup during extended runs.

This drill bit is intended for use in screw machine operations, drill presses, and CNC drilling setups where a stub-length tool is preferred for rigidity. The shorter overall length compared to jobber-length bits minimizes deflection in deep or repetitive hole applications. With a straight-cylindrical shank of 0.1610 inches and a flute length of 1.0625 inches, this bit fits standard drill chucks and collet holders without modification. It is sold individually but requires a minimum order quantity of 12 units.

Key Features

• 135-degree split point reduces drill walk and lowers entry thrust
• Web-thinned, parallel-web design improves chip flow and reduces heat
• Oxide coating provides baseline lubricity and corrosion resistance
• Screw machine length for increased rigidity and reduced deflection
• Right-hand spiral flute with straight-cylindrical shank for broad chuck compatibility
• No coolant-through requirement — suitable for dry or flood-cooled setups

Compatibility

Designed as a screw machine length replacement drill bit for applications requiring a wire size 20 diameter of 0.1610 inches, compatible with standard straight-shank drill chucks and collet systems accepting shanks in the 0.1500 to 0.2000 inch size range.

Installation Notes

Installation should be performed by a qualified machinist or tool-and-die professional. Secure the shank fully in the drill chuck or collet before operation and verify runout before beginning a production run. Power down and de-energize the machine spindle completely before changing or seating the bit. Do not exceed the recommended surface footage for high-speed steel tooling in the workpiece material being drilled.
