Hertel 83246306 Straight-flute Carbide Drill Bit No. 37

Product Description

The HERTEL 83246306 is a straight-flute carbide drill bit sized to No. 37 wire gauge, with a decimal diameter of 0.1040 inches. Built from C2 carbide grade material and left with a bright, uncoated finish, this bit delivers hard-material cutting performance in a compact, small-diameter format. The 140-degree notched point reduces thrust and improves self-centering on entry, while the web-thinned construction lowers cutting resistance in demanding materials. Two right-hand flutes evacuate chips efficiently during through-hole and blind-hole operations. Licensed machinists and tool-and-die professionals are the primary users of this bit.

This drill bit is designed for use in CNC machining centers, drill presses, and manual machines where tight-tolerance small-diameter holes are required. Primary workpiece materials include stainless steel, chrome alloy, heat-treated alloy, nickel alloy, steel, and titanium alloy. Secondary workpiece applications span the same material set, making this bit a versatile choice for aerospace, defense, medical device, and general precision machining environments where carbide tooling is specified over high-speed steel.

Key Features

• C2 carbide grade construction for cutting hard and abrasive alloys
• 140-degree notched point for reduced entry thrust and improved self-centering
• Web-thinned design lowers cutting resistance in tough materials
• Bright, uncoated finish suited to applications where coating buildup or heat transfer is a concern
• Diameter tolerance held to +0.0000 to -0.0005 inches for precision-fit hole requirements
• Right-hand cut with two flutes for controlled chip evacuation

Compatibility

Designed as a straight-flute carbide drill bit for use in standard drill chucks and collets accepting a 0.1040-inch shank diameter, compatible with CNC and manual machines tooled for No. 37 wire-gauge carbide bits.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or tooling technician familiar with carbide tooling practices. Secure the shank firmly in the appropriate collet or drill chuck to the machine manufacturer's specifications before operation. Carbide bits are brittle compared to high-speed steel and are sensitive to side-loading and impact — avoid interrupted cuts without confirming the grade is rated for that application. Always verify spindle speed and feed rate are set to values appropriate for the workpiece material and bit diameter before engaging the cut.
