Hertel 02387462 Screw Machine Drill Bit Size 53 Tin Hss

Product Description

The HERTEL 02387462 is a screw machine length drill bit designed for high-speed, close-tolerance drilling in metal and similar materials. Built from high-speed steel with a titanium nitride (TiN) coating, the bit runs cooler and lasts longer between sharpenings than uncoated HSS tooling. The 135-degree split point starts on contact without a center punch, reducing walking on flat and curved surfaces. At 1.625 inches overall length, the screw machine format fits tightly in drill presses, CNC machining centers, and turret lathes where standard-length bits would interfere. This bit is sized to wire gauge Number 53, equal to 0.0595 inches in decimal.

This bit is suited for production and maintenance drilling in machine shops, manufacturing facilities, and fabrication environments. The short overall length and straight-cylindrical shank make it compatible with quick-change chucks and standard collet systems. A web-thinned, parallel-web design with a regular spiral flute promotes chip evacuation and helps prevent chip packing in shallow-to-moderate-depth holes. Licensed machinists and tool-and-die tradespeople are the primary users, though the bit also fits HVAC and sheet metal shops drilling small pilot holes in thin-gauge steel.

Key Features

• Wire gauge Number 53 size — 0.0595 inches decimal equivalent
• 135-degree split point starts on contact, no center punch required
• TiN coating increases surface hardness and extends tool life over bare HSS
• Screw machine length — 1.625 inches OAL — for use in tight-clearance setups
• Web-thinned parallel web with regular spiral flute for consistent chip removal
• Right-hand cutting direction, straight-cylindrical shank for standard chuck compatibility
• Coolant-through: No — suitable for dry or flood-coolant external applications

Compatibility

Designed as a standard screw machine length drill bit with a straight-cylindrical shank sized at 0.0595 inches, compatible with any chuck or collet system that accepts that shank diameter in drill presses, CNC lathes, turret machines, and handheld drill drivers.

Installation Notes

This bit is installed and changed by machinists or qualified tradespeople following standard toolroom safety practices. Secure the shank fully in the chuck or collet before running the spindle. Inspect the cutting edges and TiN coating before each use — chipped or worn edges reduce hole accuracy and increase heat buildup. Operate at spindle speeds appropriate for the workpiece material and bit diameter; consult published HSS speed-and-feed tables for small-diameter bits in steel and non-ferrous metals.
