Hertel 16705097 Screw Machine Drill Bit Size 41 Carbide

Product Description

The HERTEL 16705097 is a solid carbide screw machine length drill bit sized to wire gauge 41 (0.0960 inches decimal equivalent). Built for short-hole drilling in tight-tolerance applications, this stub-length bit delivers improved rigidity over jobber-length designs, reducing deflection and runout when drilling hard or abrasive materials. The 135-degree split-point geometry allows the bit to self-center on entry without a pilot hole, making it well suited to production and precision drilling environments. The bright, uncoated finish keeps heat-treat properties intact and is appropriate for use with cutting fluids. Two flutes with a slow spiral provide efficient chip evacuation in difficult-to-machine workpiece materials.

This bit is intended for drilling cast iron, nickel alloys, stainless steel, titanium alloys, and tool steel — materials that demand the hardness and wear resistance of solid carbide over high-speed steel. Screw machine length drill bits are commonly used in CNC machining centers, drill presses, and screw machine operations where stub-length rigidity is required. The straight cylindrical shank accepts standard drill chucks and collet systems without modification.

Key Features

• Wire gauge 41 size, 0.0960 inches decimal equivalent
• 135-degree split-point tip for self-centering entry without a pilot hole
• Solid carbide construction for high wear resistance in hard and abrasive materials
• Slow spiral flute geometry promotes chip control in tough workpiece materials
• Bright, uncoated finish compatible with cutting fluid use
• Right-hand cut, straight cylindrical shank fits standard chucks and collets

Compatibility

Designed as an OEM-style replacement screw machine length drill bit for use in standard drill chucks and collet holders accepting a straight cylindrical shank at the 0.0960-inch diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Confirm the shank is fully seated and the chuck is tightened to the machine specification before starting the cut. Use an appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
