Hertel 83246389 Carbide Die Drill Bit 0.1360 in No. 29

Product Description

The HERTEL 83246389 is a solid carbide straight-flute die drill bit designed for precision drilling in hard and abrasion-resistant materials. Built from C2-grade carbide with a bright finish, this bit features a 140-degree notched point and web-thinned geometry for clean entry and reduced thrust in demanding applications. The 0.1360-inch diameter corresponds to a No. 29 wire gauge size, with a tight diameter tolerance of +0.0000 to -0.0005 inches for consistent, repeatable hole sizing. Right-hand cutting direction and a two-flute configuration make it well-suited for controlled material removal in tooling, die work, and precision machining environments.

This drill bit is intended for use in professional machining and toolroom applications where close tolerances are required. Primary workpiece materials include chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy. Its straight-flute design makes it especially effective in die and mold drilling operations where chip control and hole accuracy are critical. Machinists, tool-and-die makers, and precision fabricators working with CNC machines, drill presses, or manual mill setups will find this bit appropriate for production and repair work.

Key Features

• Solid C2-grade carbide construction for hardness and wear resistance in tough alloys
• 140-degree notched point reduces thrust and improves centering on entry
• Web-thinned geometry lowers cutting resistance and extends tool life
• Tight diameter tolerance of +0.0000 to -0.0005 inches ensures precision hole sizing
• Bright finish straight-flute design suited for die and toolroom drilling operations
• Right-hand cut, two-flute configuration for controlled chip evacuation

Compatibility

Designed for drilling chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy workpieces. Suitable for use in standard drill press, CNC, and manual milling machine setups that accept 0.1360-inch shank tooling.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tool-and-die professionals. Secure the bit firmly in the chuck or collet before operation and verify runout is within acceptable limits for the application. Coolant-through capability is not supported on this bit, so appropriate external cutting fluid or lubrication should be applied when drilling hard alloys. Always follow shop safety protocols and machine manufacturer guidelines when operating at speed.
