Hertel 2387264 Screw Machine Drill Bit Size 7 Tin Hss

Product Description

The HERTEL 2387264 is a screw machine length drill bit designed for high-speed, short-hole drilling in metalworking and machining applications. It is made from high-speed steel (HSS) with a titanium nitride (TiN) coating that extends cutting life and reduces friction against the workpiece. The bit measures 0.2010 inches in diameter (wire size 7) with an overall length of 2.25 inches and a flute length of 1.1875 inches. The 135-degree split point with web thinning allows the bit to start on contact without center-punching, reducing walking on flat surfaces. A straight-cylindrical shank seats securely in standard drill chucks and machine spindles.

Screw machine length drill bits are shorter and more rigid than jobber-length bits, making them well-suited for CNC machining centers, turret lathes, drill presses, and screw machines where reduced deflection and tight tolerances matter. This bit is appropriate for drilling into ferrous and non-ferrous metals, plastics, and similar materials at production volumes. The right-hand spiral flute efficiently evacuates chips during through-hole and blind-hole operations. It is typically purchased by machinists, tool-and-die professionals, and production shop technicians.

Key Features

• TiN coating increases surface hardness and reduces friction for longer tool life
• 135-degree split point with web thinning starts on contact and reduces thrust force
• Screw machine (stub) length provides greater rigidity and less deflection than jobber-length bits
• Right-hand regular spiral flute promotes efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks and machine tool spindles
• Parallel web configuration for consistent point geometry throughout the bit life

Compatibility

Designed as an OEM-style replacement or production consumable for use in standard drill chucks and machine spindles accepting a 0.2010-inch straight-cylindrical shank.

Installation Notes

Installation is performed by machinists or machine operators using a standard drill chuck or collet system rated for the shank diameter. Always power down and lock out the machine before changing tooling. Ensure the shank is fully seated and the chuck is tightened evenly before resuming operation. Do not exceed the recommended RPM for the material being drilled when using HSS tooling.
