Hertel 89320691 Screw Machine Drill Bit Wire 14 Hss

Product Description

The HERTEL 89320691 is a screw machine length drill bit manufactured from high-speed steel (HSS) for general-purpose drilling applications. Screw machine length bits are shorter than jobber-length bits, providing greater rigidity and reduced deflection in production and machine-tool environments. This bit carries a wire gauge size of 14, which corresponds to a decimal diameter of 0.182 inches, and features a standard 118-degree split-point angle suitable for drilling into mild steel, aluminum, brass, and similar materials. The bright, uncoated finish means the bit ships without a surface treatment, keeping costs down for high-turnover tooling inventories. Overall length is 2.1875 inches with a flute length of 1.125 inches.

Screw machine length drill bits are a standard toolroom and production-floor consumable. This bit is suited for use in drill presses, CNC machining centers, turret lathes, and automatic screw machines where short-length tooling is preferred for stub-hole and through-hole operations in light to medium-duty material. Machinists, tool-and-die workers, and maintenance technicians commonly stock wire-gauge series bits for precision hole sizing that fractional sizes cannot achieve.

Key Features

• Wire gauge size 14 with 0.182 inch decimal diameter for precision hole sizing
• High-speed steel construction provides adequate hardness and toughness for general-purpose metalworking
• 118-degree point angle is a versatile geometry suited for a wide range of common metals and plastics
• Screw machine length body reduces deflection and improves rigidity compared to jobber-length bits
• Bright, uncoated finish — no coating buildup to alter cutting diameter
• Right-hand cut for use in standard clockwise-rotating spindles

Compatibility

Designed as a general-purpose screw machine length drill bit for use in any standard drill press, CNC machining center, turret lathe, or automatic screw machine accepting round-shank tooling of 0.182 inch diameter.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or maintenance technician familiar with rotating tooling safety practices. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the bit firmly in the chuck or collet to the full recommended grip depth to prevent pullout during cutting. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life and maintain dimensional accuracy.
