Precision Twist Drill 091535 Hss Silver Deming Jobber Drill

Product Description

The PRECISION TWIST DRILL 091535 is a high-speed steel (HSS) Silver and Deming jobber-length drill bit with a 1/2 inch reduced parallel shank. Designed with a 35/64 inch diameter tip and a 4 inch depth of cut, this bit delivers consistent cutting performance across a range of metalworking and fabrication applications. The 3-flute construction promotes efficient chip evacuation, and the HSS composition provides high resistance to abrasion during extended use. Licensed tradespeople and industrial maintenance techs rely on this bit for precision hole drilling in ferrous and non-ferrous materials.

This Silver and Deming style drill bit is suited for metalworking, maintenance, and fabrication tasks where a reduced-shank bit is required to fit standard 1/2 inch chuck equipment. The jobber-length body provides a practical balance between reach and rigidity. It is commonly used in machine shops, plant maintenance environments, and on-site mechanical work where drilling through thicker stock is required. The 3-flute geometry makes it particularly effective in softer metals and plastics where fast chip clearance improves bore quality.

Key Features

• 35/64 inch diameter tip for precise, consistent hole sizing
• 4 inch depth of cut supports drilling through thicker workpieces
• 1/2 inch reduced parallel shank fits standard 1/2 inch chucks
• 3-flute design promotes fast chip evacuation and cleaner bores
• HSS construction delivers high abrasion resistance for extended service life
• Jobber length provides a balance of reach and stability

Compatibility

Designed for use with standard 1/2 inch drill chucks on corded drills, drill presses, and milling machines commonly found in metalworking and industrial maintenance applications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tradespeople familiar with proper drilling techniques and equipment operation. Ensure the drill press or handheld drill is powered off and secured before mounting or removing the bit from the chuck. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and maintain bore quality. Always wear appropriate PPE including eye protection when operating rotary cutting tools.
