Hertel 2386167 Screw Machine Drill Bit Size 9 Hss

Product Description

The HERTEL 2386167 is a screw machine length drill bit designed for high-throughput drilling in metal fabrication, machining, and general industrial applications. Built from high-speed steel with an oxide finish, this wire gauge Size 9 bit measures 0.1960 inches in diameter and 2.25 inches in overall length. The 135-degree split point allows the bit to self-center on contact, reducing the need for a center punch and minimizing walking on smooth surfaces. A web-thinned, parallel-web construction reduces cutting resistance and improves chip clearance. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling operations. Machinists and fabricators working with drill presses, CNC equipment, or hand-held power tools will find this bit suited for close-tolerance work in the 0.1960-inch diameter range.

This bit is built for screw machine and production drilling environments where a shorter overall length provides added rigidity and reduced deflection. The straight-cylindrical shank accepts standard drill chucks without modification. Typical applications include drilling pilot holes, clearance holes, and through holes in mild steel, aluminum, brass, and similar materials. The oxide coating provides moderate lubricity and corrosion resistance, extending service life in dry or light-lubrication cutting conditions. This is a single-piece package sold in multiples of 12, making it practical for stocking production drilling cells or maintenance toolboxes.

Key Features

• Wire gauge Size 9, 0.1960-inch diameter for close-tolerance hole production
• 135-degree split point self-centers and reduces drill walk on entry
• Web-thinned parallel web lowers thrust requirements and improves chip evacuation
• High-speed steel construction with oxide finish for moderate heat and wear resistance
• Screw machine length at 2.25 inches overall for maximum rigidity and reduced deflection
• Right-hand spiral flutes with 1.1875-inch flute length suit through-hole and blind-hole work

Compatibility

Designed as a direct-fit replacement or stocking drill bit for standard drill chucks accepting a 0.1960-inch straight-cylindrical shank, suitable for drill presses, screw machines, CNC drilling centers, and portable power drills used in metal fabrication and maintenance applications.

Installation Notes

Installation and replacement should be performed by a qualified machinist or maintenance technician. Ensure the drill press, CNC spindle, or power tool is fully de-energized and locked out before changing bits. Seat the straight-cylindrical shank fully and evenly in the chuck and verify tightness before operation. Follow applicable shop safety standards and machine manufacturer guidelines for cutting speed and feed rate selection.
