Precision Twist Drill 6000111 Reduced Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6000111 is a reduced shank drill bit designed for general-purpose drilling in ferrous metals, aluminum, copper, and a wide range of other materials. The bit measures 1-5/32 inches (1.1562 inches decimal) in cutting diameter with a 3/4-inch straight-cylindrical shank, allowing it to seat in standard drill chucks despite the larger cutting diameter. The 118-degree standard point angle suits most common shop and field drilling applications. Overall length is 6 inches with a 3-inch flute length. Constructed from high speed steel with a bright uncoated finish, this bit delivers reliable performance across trade and light industrial environments. It is part of the Series R58 line and cuts in a right-hand direction with a regular spiral flute.

This drill bit is suited for drilling through ferrous metals including steel and iron, as well as secondary materials such as aluminum, copper, magnesium, nickel, titanium, and synthetic materials. The reduced shank design makes it practical for use in standard 3/4-inch capacity drill chucks where a full-shank bit of this diameter would not fit. It is commonly used by maintenance mechanics, pipefitters, millwrights, and general trade professionals who need to produce holes larger than 1 inch using conventional drilling equipment. The 3-inch maximum drilling depth supports through-drilling in typical structural and plate stock thicknesses encountered in trade work.

Key Features

• 1-5/32 inch (1.1562 inch decimal) cutting diameter with 3/4-inch reduced shank for use in standard drill chucks
• 118-degree standard point angle for general-purpose entry into ferrous and non-ferrous materials
• High speed steel construction provides durability across a broad range of workpiece materials
• Right-hand cut with regular spiral flute for consistent chip evacuation
• Bright uncoated finish — no coating degradation concerns during regrinding
• 6-inch overall length with 3-inch flute length suits most standard drilling setups

Compatibility

Designed for use in 3/4-inch capacity drill chucks on corded drills, drill presses, and magnetic base drills. Compatible with ferrous metals, aluminum, copper, magnesium, nickel, titanium, and synthetic materials per manufacturer specifications. Meets ANSI standards.

Installation Notes

Secure the reduced shank fully into the drill chuck and tighten with a chuck key before operation. De-energize and lock out any stationary drilling equipment before changing bits. Use appropriate workholding — clamp the workpiece rather than holding it by hand when drilling at this diameter. Cutting fluid or coolant is not required for this bit but may extend service life when drilling harder ferrous stock.
