Precision Twist Drill 6000350 Reduced Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6000350 is a reduced shank cobalt drill bit engineered for demanding drilling applications in ferrous and non-ferrous metals. The bit measures 11/16 inch (0.6875 inch) in diameter with a 1/2 inch straight-cylindrical reduced shank, making it compatible with standard 1/2 inch drill chucks. The 118-degree split point promotes self-centering and reduces walking on entry, while the cobalt construction provides heat and wear resistance needed when cutting hard or abrasive materials. Machinists, maintenance technicians, and metalworking shops are the primary installers of this tool.

The Series R56CO is designed for drilling ferrous metals as its primary application, and also performs in aluminum, copper, magnesium, nickel, titanium, and synthetic materials. The reduced shank design allows a large-diameter bit to seat in a standard 1/2 inch chuck, expanding drilling capacity without requiring a larger machine spindle. This makes it practical for drill presses, lathes, and handheld magnetic drills used in fabrication and maintenance work. The bright uncoated finish is suited to applications where a coating is not required or where re-sharpening is anticipated.

Key Features

• Cobalt tool material for high heat resistance and extended tool life in hard metals
• 118-degree split point for reduced thrust and self-centering on entry
• Reduced shank at 1/2 inch diameter allows use in standard 1/2 inch chucks
• Right-hand spiral flute with regular helix for efficient chip evacuation
• 3 inch flute length supports drilling to a maximum depth of 3 inches
• Bright uncoated finish allows easy re-sharpening and visual wear inspection
• ANSI standard compliance for consistent dimensional accuracy

Compatibility

Designed for use with drill presses, lathes, and handheld drills fitted with 1/2 inch chucks. Primary workpiece material is ferrous metal; secondary compatible materials include aluminum, cermet, copper, magnesium, nickel, synthetic materials, and titanium.

Installation Notes

This bit is installed by machinists or qualified maintenance technicians. Secure the reduced shank firmly in a 1/2 inch chuck and verify runout before drilling. Power down and lock out the machine before changing bits. Use appropriate cutting fluid or coolant for the workpiece material when extended cuts are performed, even though the bit is rated for dry use.
