Hertel 83246512 Straight-flute Drill Bit Wire 16 Carbide

Product Description

The HERTEL 83246512 is a straight-flute solid carbide drill bit designed for precision drilling in tough ferrous and exotic materials. Sized to wire gauge number 16 (0.1770 inches decimal), this bit features a 140-degree notched point and a web-thinned geometry that reduces thrust and improves centering on entry. The C2 carbide grade provides the hardness and wear resistance needed for high-performance drilling in production and maintenance environments. With a right-hand cutting direction and two flutes, it suits conventional drill presses, CNC machining centers, and hand-held electric drills running at appropriate speeds for carbide tooling.

This drill bit is rated for use in chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy workpieces. It fits applications in aerospace component fabrication, industrial maintenance, and precision metalworking shops where hole tolerances and tool life in hard materials are critical. The bright uncoated finish leaves the carbide substrate exposed, which is typical for applications where coating buildup could affect hole diameter consistency or where re-sharpening is anticipated.

Key Features

• Wire gauge number 16 drill size, 0.1770 inches decimal diameter with a tight tolerance of +0.0000 to -0.0005 inches
• 140-degree notched point geometry reduces entry thrust and improves drill stability
• Web-thinned construction lowers cutting resistance in hard and work-hardening alloys
• C2 solid carbide construction delivers extended tool life compared to high-speed steel in abrasive materials
• Bright uncoated finish maintains dimensional accuracy and supports re-sharpening
• Right-hand cutting direction, compatible with standard drill chucks and spindles

Compatibility

Designed for drilling chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy workpieces as an OEM-style straight-flute carbide drill bit for wire-gauge drilling applications.

Installation Notes

Carbide drill bits require rigid machine setups to avoid chipping the cutting edge — avoid use in hand drills where lateral deflection cannot be controlled. Secure the workpiece firmly and confirm spindle runout is within acceptable limits before drilling. For stainless steel and nickel alloys, use a cutting fluid rated for those materials to manage heat and prevent work hardening at the hole entrance. Always wear appropriate eye protection and follow shop safety procedures when operating rotary cutting tools.
