Triumph Twist Drill 012611 Wire Size 11 Hss Drill Bit

Product Description

The TRIUMPH TWIST DRILL 012611 is a jobber-length drill bit designed for high-performance drilling in metal and wood applications. Built from M7 high speed steel with an oxide and gold coating, this bit handles alloy steel, carbon steel, and wood with consistent results. The 135-degree split point reduces walking and allows self-centering starts without a center punch. The web-thinned, tapered web design reduces feed force and improves chip clearance. At 3.5 inches overall length with a 2.3125-inch flute, it fits standard jobber-length chucks and drill presses used across machining and fabrication trades.

This bit is suited for production drilling and general-purpose work in alloy steel, carbon steel, and wood. The right-hand spiral flute and straight cylindrical shank make it compatible with standard drill chucks on hand drills, drill presses, and CNC equipment. Its heavy-duty grade and high-performance designation place it in maintenance, fabrication shop, and light industrial settings where wire-gauge sizing is required. Wire size 11 corresponds to 0.191 inches decimal, a common gauge in tapping and clearance-hole applications for small fasteners.

Key Features

• M7 high speed steel construction for durability in ferrous and non-ferrous materials
• Oxide and gold coating reduces friction and extends bit life
• 135-degree split point with web thinning for self-centering starts and reduced thrust
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Straight cylindrical shank fits standard drill chucks without adapters
• Wire size 11 at 0.191 inches decimal for precise gauge-specific hole requirements

Compatibility

Designed as an OEM-style jobber-length drill bit for use in standard three-jaw drill chucks on hand drills, drill presses, and compatible CNC spindles accepting straight cylindrical shanks.

Installation Notes

Secure the shank firmly in the drill chuck before operation and verify chuck key is removed prior to starting the drill. Use cutting fluid or coolant when drilling steel to manage heat and extend bit life. Run at speeds appropriate for the workpiece material and bit diameter following standard machinist speed-and-feed tables. Inspect the cutting edge and coating before each use and replace if chipping or excessive wear is observed.
