Hertel 74132465 Screw Machine Drill Bit Size 48 Cobalt

Product Description

The HERTEL 74132465 is a screw machine length drill bit designed for high-productivity drilling in tight clearance applications where a standard-length bit is too long. Built from cobalt high-speed steel and finished with a titanium aluminum nitride (TiAlN) coating, this bit handles harder workpiece materials and elevated cutting temperatures without premature edge breakdown. It is wire gauge size 48, measuring 0.0760 inches in diameter, with a 135-degree split point that self-centers on contact and reduces thrust load. Overall length is 1-11/16 inches with a 11/16-inch flute. The straight cylindrical shank seats directly into standard drill chucks or quick-change systems used on CNC machines, drill presses, and hand drills.

This screw machine length drill bit suits production-floor and maintenance shop environments where space constraints call for a shorter tool. Typical applications include drilling in metals such as stainless steel, alloy steel, cast iron, and hardened materials where cobalt composition and TiAlN coating provide heat and wear resistance. It is commonly used by machinists, tool-and-die technicians, and maintenance mechanics. Right-hand cutting direction, regular spiral flute geometry, and web-thinned parallel web construction support consistent chip evacuation during through-hole and blind-hole drilling operations.

Key Features

• Cobalt high-speed steel construction for improved heat resistance in hard-material drilling
• TiAlN coating extends tool life by reducing friction and resisting thermal wear at the cutting edge
• 135-degree split point self-centers on the workpiece and reduces entry thrust
• Screw machine length body at 1-11/16 inches OAL improves rigidity and suits tight-clearance setups
• Web-thinned parallel web lowers cutting resistance and improves chip flow
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-style replacement or direct-use screw machine length drill bit for standard drill chucks and quick-change toolholders accepting a straight cylindrical shank in the 0.0760-inch wire gauge size 48 diameter class.

Installation Notes

Installation and use should be performed by qualified machinists or mechanical tradespeople familiar with cutting tool practices. Secure the shank fully in the chuck and verify runout before beginning a cut. Power down and lock out the machine before changing bits. Follow applicable shop safety standards and manufacturer feed-and-speed guidelines for cobalt tooling when setting spindle speed and feed rate.
