Precision Twist Drill 091542 Hss Silver Deming Jobber Drill

Product Description

The PRECISION TWIST DRILL 091542 is a high-speed steel (HSS) Silver and Deming jobber-length drill bit with a 1/2-inch reduced parallel shank. Designed for demanding metal drilling applications, it features a 21/32-inch diameter tip and a 4-inch depth of cut with an overall length of 6 inches. The 3-flute construction promotes efficient chip evacuation and is built for high resistance to abrasion during extended use. This bit is a reliable choice for machinists, maintenance technicians, and metalworking tradespeople who require consistent performance when drilling through ferrous and non-ferrous materials.

This drill bit is suited for general-purpose jobber-length drilling tasks in industrial, commercial, and trade shop environments. The 1/2-inch reduced shank allows it to be used in standard 1/2-inch drill chucks even though the cutting diameter exceeds that dimension, making it practical for technicians working with common hand drills, drill presses, and milling setups. It is sold individually and is appropriate for high-volume drilling operations where abrasion resistance is a priority.

Key Features

• HSS Silver and Deming construction provides high abrasion resistance during heavy-duty drilling
• 3-flute design promotes efficient chip removal and reduces heat buildup
• 21/32-inch cutting diameter with a 1/2-inch reduced parallel shank for use in standard chucks
• 4-inch depth of cut suits deeper bore applications common in trade and industrial work
• Overall length of 6 inches for reach in standard drill press and hand drill setups
• Jobber length configuration for versatile, general-purpose metal drilling

Compatibility

Designed as a general-purpose OEM-style jobber drill bit compatible with 1/2-inch drill chucks on hand drills, drill presses, and milling equipment used in metalworking and trade applications.

Installation Notes

Installation and use should be performed by a qualified machinist or trade technician familiar with cutting tool safety. Ensure the drill chuck is fully secured and the workpiece is properly clamped before operation. Always wear appropriate eye protection and follow applicable OSHA and shop safety guidelines when operating drill equipment. Inspect the cutting edges for wear or damage before each use and replace if chipping or dulling is observed.
