Hertel 83246447 Straight-flute Drill Bit Wire 23 Carbide

Product Description

The HERTEL 83246447 is a straight-flute, solid carbide drill bit designed for precision drilling in hard and difficult-to-machine materials. Built from C2-grade carbide, this bit measures 0.154 inches in diameter (wire size 23) and features a 140-degree notched point for accurate self-centering and reduced thrust on entry. The web-thinned construction lowers cutting resistance and improves chip evacuation in demanding applications. Right-hand cutting direction is standard. The bright, uncoated finish suits use in dry or minimally lubricated conditions. Licensed machinists, tool-and-die technicians, and maintenance trades install this bit where tight tolerances and material hardness rule out standard high-speed steel tooling.

This drill bit is intended for production and precision machining operations involving chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, titanium alloy, and similar ferrous and high-strength materials. The 0.154-inch diameter and straight-flute geometry make it well suited to short-hole drilling, jig work, and fixture applications where hole location and diameter tolerance control are critical. The diameter tolerance of +0.0000 to -0.0005 inches supports close-fit hole requirements without reaming in some applications.

Key Features

• Solid C2-grade carbide construction for hardness and wear resistance in alloy and stainless steel drilling
• 140-degree notched point promotes accurate entry and reduces walking on hard surfaces
• Web-thinned design lowers cutting thrust and improves chip flow in straight-flute geometry
• Tight diameter tolerance of +0.0000 to -0.0005 inches for controlled hole sizing
• Bright, uncoated finish compatible with dry cutting and standard cutting fluids
• Right-hand cutting direction; 2-flute configuration standard for straight-flute drills

Compatibility

Designed as a direct-replacement or standard-stock straight-flute carbide drill bit for machining operations in chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy workpieces where wire size 23 diameter is specified.

Installation Notes

Installation and use should be performed by qualified machinists or tool technicians familiar with carbide tooling requirements. Secure the shank firmly in a compatible drill chuck or collet rated for the 0.154-inch shank diameter before use. Carbide bits are brittle and susceptible to fracture under side-load or impact; avoid interrupted cuts without confirming suitability. Always verify spindle speed and feed rate against the workpiece material before engaging the cut.
