Hertel 16704983 Screw Machine Drill Bit No. 32 Solid Carbide

Product Description

The HERTEL 16704983 is a screw machine length drill bit ground from solid carbide and designed for high-performance drilling in hard and abrasive workpiece materials. With a 135-degree split-point angle, the bit self-centers on entry and reduces thrust force, making it well suited for production environments where cycle time and hole accuracy matter. The bit measures 1.875 inches overall length with a 0.875-inch flute length, carries a bright uncoated finish, and features a slow-spiral two-flute geometry optimized for chip evacuation in difficult-to-machine materials. Machinists, toolroom technicians, and CNC operators typically apply this bit in precision drilling operations.

This bit is sized to wire gauge No. 32, corresponding to a decimal diameter of 0.116 inches. It is intended for drilling cast iron, nickel alloys, stainless steel, titanium alloys, and tool steel. The straight cylindrical shank fits standard drill chucks and collet-style toolholders used on CNC machining centers, drill presses, and manual lathes. The screw machine length body — shorter than jobber length — provides added rigidity, which reduces deflection and extends tool life when working in tough alloys or when drilling at depth-to-diameter ratios common in production runs.

Key Features

• Solid carbide construction for superior hardness and wear resistance in abrasive materials
• 135-degree split-point geometry for self-centering entry and reduced thrust
• Slow-spiral two-flute design promotes chip clearance in cast iron, stainless steel, and titanium alloys
• Screw machine length body provides added rigidity versus jobber-length bits, reducing deflection
• Bright uncoated finish — suitable for use with cutting fluids; no coating buildup in small-diameter flutes
• Right-hand cut with straight cylindrical shank for universal toolholder compatibility

Compatibility

Designed for use in standard drill chucks and collet toolholders accepting a straight cylindrical shank. Suitable for machining cast iron, nickel alloys, stainless steel, titanium alloys, and tool steel. Confirm chuck capacity supports the 0.116-inch shank diameter before use.

Installation Notes

Installation of this bit is performed by qualified machinists or toolroom personnel. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the toolholder. Use appropriate cutting fluid or coolant for the workpiece material, particularly when drilling stainless steel or titanium alloys, to manage heat buildup. Do not exceed the recommended feed and speed parameters for solid carbide tooling in the workpiece material being drilled.
