Hertel 83246140 Straight-flute Drill Bit No. 53 Carbide

Product Description

The HERTEL 83246140 is a straight-flute drill bit designed for precision drilling in hard and difficult-to-machine materials. It carries a No. 53 wire gauge size with a decimal diameter of 0.0595 inches and is manufactured from C2 carbide for extended tool life in demanding applications. The 140-degree notched point geometry reduces thrust and improves self-centering at entry, while the web-thinned design supports chip evacuation in tough alloys. The bright, uncoated finish is suitable for use with cutting fluid. This bit is installed by machinists, tool-and-die technicians, and precision fabricators working with tight-tolerance drilling operations.

This drill bit is intended for use on chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy workpieces. Its straight-flute configuration makes it well suited for short-chipping materials where standard spiral flutes may pack or deflect. Typical applications include aerospace component drilling, precision machined parts, and any setup requiring consistent hole size at small diameters. Right-hand cutting direction is standard for conventional drill press, CNC, and manual lathe operations.

Key Features

• C2 carbide construction for durability in hard and abrasion-resistant workpiece materials
• 140-degree notched point reduces entry thrust and improves hole location accuracy
• Web-thinned geometry supports chip flow and lowers cutting forces in dense alloys
• Straight-flute design optimized for short-chipping materials such as stainless steel and titanium alloy
• Bright uncoated finish compatible with a range of cutting fluids and lubricants
• Diameter tolerance of +0.0000 to -0.0005 inches for consistent, repeatable hole sizing

Compatibility

Designed for use in chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy workpieces as a No. 53 wire gauge straight-flute carbide drill bit in standard drill chucks accepting a 0.0595-inch shank diameter.

Installation Notes

This bit is installed by machinists and precision fabricators using drill presses, CNC machining centers, or manual lathes with an appropriately sized collet or drill chuck. Secure the workpiece firmly before beginning any drilling operation. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality. Inspect the cutting edges before use and replace the bit at the first sign of chipping or dimensional drift.
