Hertel 61699138 Screw Machine Drill Bit 0.113in Hss

Product Description

The HERTEL 61699138 is a screw machine length drill bit designed for high-speed steel cutting in general purpose drilling applications. With a 0.113 inch (wire gauge #33) diameter and a 118-degree standard point angle, this bit delivers consistent, accurate entry in a compact 1-7/8 inch overall length. The oxide finish provides basic surface protection and reduces friction during operation. The right-hand spiral flute geometry with a regular spiral type promotes efficient chip evacuation. This bit is a single-piece unit suited for use by machinists, tradespeople, and maintenance professionals working with drill presses, CNC machines, or handheld power tools.

Screw machine length drill bits are shorter than jobber-length bits, making them well suited for work in confined spaces or where rigidity and reduced deflection are priorities. The 7/8 inch flute length and 3xD flute-by-diameter ratio are sized for shallow-to-moderate depth holes. This bit falls within the 0.1000 to 0.1500 inch decimal inch size range and is built to ANSI specification, making it a standard fit for general manufacturing, maintenance, and repair operations. It is sold individually with a minimum order quantity of 12 units.

Key Features

• Wire gauge #33 diameter: 0.113 inches for precise small-diameter drilling
• 118-degree standard point angle for general purpose entry on a wide range of materials
• High speed steel construction for durability across common metals and plastics
• Oxide finish reduces surface friction and provides corrosion resistance
• Short screw machine length (1-7/8 inches overall) for improved rigidity and reduced deflection
• Straight-cylindrical shank compatible with standard drill chucks
• ANSI specification designation for dimensional consistency

Compatibility

Designed as a general purpose replacement or stock drill bit for use in standard drill chucks accommodating a straight-cylindrical shank within the 0.1000 to 0.1500 inch decimal inch size range.

Installation Notes

This bit is installed by a machinist or qualified tradesperson into a drill press, lathe tailstock, or handheld power tool with a compatible chuck. Ensure the spindle is fully stopped and power is disconnected before changing bits. Secure the shank firmly in the chuck to prevent slippage during operation. Follow applicable workplace safety standards and manufacturer guidelines for cutting speed and feed rate based on the workpiece material.
