Cle-line C21131 Jobber Length Drill Bit Set 25 Pc Metric

Product Description

The CLE-LINE C21131 is a 25-piece jobber length drill bit set designed for metalworking and general-purpose drilling applications. The set spans a metric range from 1 mm to 13 mm in 0.5 mm step increments, covering 25 individual sizes in decimal-inch equivalents from 0.0394 to 0.5118 inches. Bits are machined from high-speed steel with an oxide finish that reduces friction and provides basic corrosion resistance during service. Each bit features a straight shank, a 118-degree radial point, and right-hand cutting direction. The set ships in a metal storage case and is built to the Series 1899 standard.

This set is suited for metalworking and multipurpose drilling tasks in trade and light industrial environments. The metric sizing sequence and 13 mm maximum shank diameter make it a practical choice for machinists, fabricators, maintenance technicians, and multi-trade professionals who work to metric specifications. The 118-degree general-purpose point geometry handles a wide range of common base metals and general materials without requiring a secondary grind.

Compatibility

Designed as a general-purpose jobber length drill bit set for use in standard drill chucks accommodating straight-shank bits up to 13 mm in diameter, suitable for metalworking and multipurpose drilling applications.

Installation Notes

Install bits in a drill press, hand drill, or milling machine chuck rated for the shank diameter before tightening the chuck securely. Confirm the machine is fully powered down and the chuck is stationary before changing bits. Use appropriate cutting fluid or coolant for the base metal being drilled to extend bit life. Secure workpieces with clamps or a vise before drilling to prevent movement.
