Precision Twist Drill 6000049 Reduced Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6000049 is a reduced shank drill bit designed for general-purpose drilling in ferrous metals and a wide range of secondary materials. The 1-inch cutting diameter pairs with a 3/4-inch straight-cylindrical shank, allowing the bit to fit standard chuck sizes while drilling larger holes. High speed steel construction provides the toughness needed for repeated use in production and service environments. The 118-degree standard point angle gives clean entry on most metals without requiring a center punch on flat stock. Overall length is 6 inches with a 3-inch flute length, keeping chip evacuation efficient at typical drilling depths.

This bit suits applications in HVAC, plumbing, and electrical trades where holes larger than 3/4 inch are needed and a full-shank bit would require a larger chuck. The reduced shank design lets a standard 3/4-inch drill chuck handle a 1-inch cut, making it practical for portable drills and drill presses commonly found on job sites. Compatible materials include ferrous metal, aluminum, copper, nickel, titanium, magnesium, and synthetic materials. The right-hand spiral flute with regular helix clears chips efficiently in through-hole and blind-hole drilling scenarios.

Key Features

• 1-inch cutting diameter with 3/4-inch reduced straight-cylindrical shank for standard chuck compatibility
• High speed steel construction for durability across ferrous and non-ferrous materials
• 118-degree standard point angle for general-purpose use on flat and curved stock
• Right-hand cut with regular spiral flute for consistent chip removal
• Bright/uncoated finish — no coating buildup to affect dimensional tolerances
• ANSI standard compliant, Series R58

Compatibility

Designed for use in 3/4-inch or larger drill chucks on portable drills and drill presses. Suitable for drilling ferrous metal, aluminum, copper, magnesium, nickel, titanium, and synthetic materials in general-purpose applications.

Installation Notes

Install and removal should be performed with the drill unplugged or locked out per standard OSHA lockout/tagout procedures. Secure the shank fully in the chuck jaws before operating. Use cutting fluid on harder ferrous materials to extend tool life and improve finish quality. Maximum drilling depth should not exceed the 3-inch flute length to maintain chip clearance.
