Precision Twist Drill 6000043 Reduced Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6000043 is a reduced shank drill bit designed for general-purpose drilling in ferrous metals, aluminum, copper, nickel, titanium, and other materials. It features a 7/8-inch cutting diameter with a 1/2-inch Weldon flat shank, allowing it to fit standard 1/2-inch chuck machines while drilling larger-diameter holes. The 118-degree standard point angle suits a wide range of workpiece materials. Built from high speed steel with a bright uncoated finish, this bit is suited for production and maintenance environments where reliable, consistent hole quality is required. Licensed HVAC, plumbing, and mechanical tradespeople regularly reach for this style of bit when working with sheet metal, pipe flanges, and structural steel.

The 6000043 belongs to the Series R57 line of reduced shank bits. It is appropriate for use in residential and commercial trade applications where a full-shank bit of 7/8-inch diameter would exceed the machine's chuck capacity. With a 3-inch flute length and a 6-inch overall length, it handles moderate drilling depths in plate stock, angle iron, conduit hangers, and similar ferrous or non-ferrous workpieces. The right-hand spiral flute geometry clears chips efficiently during through-hole and blind-hole operations.

Key Features

• 7/8-inch cutting diameter with a reduced 1/2-inch Weldon flat shank for use in standard 1/2-inch capacity drills and drill presses
• 118-degree standard point angle for general-purpose entry on ferrous metals and non-ferrous materials
• High speed steel construction provides durability across a broad range of workpiece materials
• 3-inch flute length supports a maximum drilling depth of 3 inches
• Right-hand cut with regular spiral flute for consistent chip evacuation
• Bright uncoated finish — no coating buildup to affect dimensional tolerances
• Meets ANSI standards; three flats on the Weldon shank prevent slippage in the chuck

Compatibility

Designed for use in 1/2-inch capacity drill presses, magnetic drills, and hand drills with Weldon-style or standard keyed chucks. Suitable for drilling ferrous metals, aluminum, cermet, copper, magnesium, nickel, synthetic materials, and titanium per Series R57 general-purpose specifications.

Installation Notes

Install the bit in a 1/2-inch Weldon-compatible chuck or standard keyed chuck, seating the flat against the set screw to prevent rotation under load. Secure the workpiece before drilling and use appropriate personal protective equipment including eye protection. Apply consistent feed pressure and allow the flute geometry to clear chips — forcing the bit increases heat and reduces tool life. No coolant is required for general use, though cutting fluid is recommended when drilling harder ferrous alloys.
