Hertel 2387272 Screw Machine Drill Bit Size 8 Hss Tin

Product Description

The HERTEL 2387272 is a screw machine length drill bit designed for high-speed, close-tolerance drilling in metal fabrication, machining, and production environments. Built from high-speed steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction during repeated use. The 135-degree split point promotes accurate self-centering without the need for a center punch, and the web-thinned construction reduces thrust requirements at the cutting edge. At 2.25 inches overall length, the short flute geometry provides added rigidity for drilling in tight clearances or on CNC screw machines and drill presses.

This drill bit is suited for production machining, job shop work, and maintenance applications where a compact, stub-length bit is required. The straight-cylindrical shank seats directly into standard drill chucks without modification. The regular spiral flute and parallel web configuration support consistent chip evacuation in ferrous and non-ferrous materials. Machinists, tool-and-die workers, and maintenance technicians are the primary installers and users of this bit.

Key Features

• TiN coating extends cutting life and reduces heat buildup compared to uncoated HSS
• 135-degree split point with web thinning allows self-centering and reduces entry thrust
• Screw machine (stub) length provides rigidity for precise, repeatable hole depth
• Straight-cylindrical shank fits standard drill chucks and CNC tool holders
• Right-hand cutting direction, regular spiral flute for standard drilling operations
• No coolant-through requirement simplifies setup on conventional equipment

Compatibility

Designed as an OEM-style replacement or standard stock drill bit for use in drill presses, CNC machining centers, and hand-held drilling equipment accepting a straight-cylindrical shank in the 0.1990-inch diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with cutting tool handling and machine operation. Secure the shank fully in the drill chuck and verify concentricity before beginning a cut. Ensure the machine is powered down and locked out before changing tooling. Follow the machine manufacturer guidelines and applicable ANSI safety standards for rotating cutting tools.
