Hertel 2386217 Screw Machine Drill Bit Size 14 Hss

Product Description

The HERTEL 2386217 is a screw machine length drill bit designed for high-productivity drilling in metal, plastic, and similar materials. Built from high-speed steel with an oxide coating, this bit handles the heat and wear demands of production drilling environments. It carries a wire gauge size 14 designation, equivalent to 0.1820 inches in decimal, and features a 135-degree split point that reduces walking and allows drilling to begin without a center punch in many applications. The web-thinned, parallel web configuration supports clean entry and efficient chip evacuation through its spiral flutes. At 2-3/16 inches overall length, this is a stub-length tool suited for close-clearance work on drill presses, CNC machines, and hand-held power tools.

Screw machine length drill bits are a standard choice in production machining, sheet metal fabrication, and light manufacturing where rigidity matters more than reach. The shorter flute length of 1-1/8 inches reduces deflection and chatter compared to jobber-length bits, making this size appropriate for repetitive hole-making tasks in both manual and automated setups. Right-hand cutting direction is standard for conventional drill press and CNC spindle rotation. This bit is sold individually but requires a minimum order of 12 units.

Key Features

• Wire gauge size 14 (0.1820 inches decimal) straight-cylindrical shank for standard chuck compatibility
• 135-degree split point reduces thrust force and minimizes bit walking on entry
• Web-thinned parallel web design promotes efficient chip evacuation and cleaner holes
• High-speed steel construction with oxide coating for heat resistance and extended tool life
• Screw machine (stub) length at 2-3/16 inches OAL increases rigidity and reduces deflection in tight clearance setups
• Right-hand spiral flute, no coolant-through — suitable for dry or flood-cooled applications using external coolant

Compatibility

Designed as a standard screw machine length drill bit for use with any drill press, hand-held power drill, or CNC machine equipped with a chuck or collet sized for a 0.1820-inch straight-cylindrical shank. Fits within the decimal inch range of 0.1500 to 0.2000 inches for this product family.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or trained trade professional familiar with rotating cutting tools. Ensure the shank is fully seated and the chuck or collet is properly tightened before operation. Select spindle speed appropriate for the workpiece material and bit diameter, and inspect the cutting edges for wear or damage before each use. Always wear appropriate eye protection and secure the workpiece to prevent movement during drilling.
