Hertel 2387322 Drill Bit Size 15 Hss Tin 135 Degree

Product Description

The HERTEL 2387322 is a screw machine length drill bit designed for high-speed, high-accuracy drilling in metal fabrication, machining, and maintenance applications. Built from high-speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during cutting. The 135-degree split point reduces walking on entry and requires less feed force than a standard 118-degree point. With an overall length of 2.1875 inches and a wire gauge size of 15 (0.1800 inch decimal equivalent), this bit is suited for machinists, maintenance technicians, and tool-and-die professionals working on production drilling tasks.

Screw machine length drill bits are shorter than jobber-length bits, giving them greater rigidity and reduced deflection in CNC machining centers, drill presses, and turret lathes. This bit is well suited for drilling through steel, aluminum, cast iron, and similar materials where hole location accuracy and chip clearance matter. The spiral flute geometry and web-thinned, parallel web configuration promote efficient chip evacuation at higher feed rates. It is a single-piece, individual unit packaged for direct bench or toolbox use.

Key Features

• TiN coating increases surface hardness and reduces heat buildup during prolonged drilling cycles
• 135-degree split point with web thinning reduces thrust force and eliminates the need for a center punch on most metals
• Screw machine length body (2.1875 inches OAL) provides greater rigidity and reduces deflection versus jobber-length bits
• Right-hand spiral flute design promotes consistent chip evacuation
• Straight-cylindrical shank fits standard 3-jaw drill chucks and collet holders without modification
• No coolant-through requirement — suitable for dry or flood-coolant environments

Compatibility

Designed as a direct-fit replacement or supplemental tooling for any drill press, CNC machining center, lathe turret, or hand drill accepting a 0.1800-inch straight-cylindrical shank in the size 15 wire gauge range.

Installation Notes

Installation and tool changes must be performed with the machine fully powered down and locked out per applicable OSHA lockout/tagout procedures. Ensure the chuck or collet is clean and free of chips before seating the shank. Inspect the cutting edges for chipping or wear before use. Do not exceed the recommended RPM range for the workpiece material and bit diameter as published in standard machinist reference tables.
