Precision Twist Drill 6000433 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6000433 is a taper shank drill bit designed for heavy-duty drilling in metal, steel, and similar materials. Built from high speed steel (HSS) with an oxide finish, this bit delivers reliable cutting performance in general-purpose machining and fabrication applications. It features a 1.25-inch diameter, a 118-degree standard point angle, and a web-thinned tip that reduces thrust and improves penetration on tough workpieces. The 3MT (Morse Taper 3) shank seats directly into compatible taper-bore spindles on drill presses, lathes, and milling machines. With an overall length of 12.5 inches, this bit handles deeper bores without extension adapters.

This bit is suited for machine shop environments, maintenance and repair operations, and fabrication facilities where large-diameter holes are drilled in ferrous and non-ferrous metals. The right-hand spiral flute with a 7.875-inch flute length efficiently evacuates chips during deep-hole drilling. The Series S209 designation places it within a well-established line of ANSI-standard taper shank drills used by machinists and toolroom professionals. It is appropriate for production drilling as well as job-shop work where consistent hole quality at 1.25 inches diameter is required.

Key Features

• 1.25-inch diameter with ANSI-standard geometry for consistent, repeatable hole sizing
• 3MT Morse Taper shank seats securely in taper-bore spindles without a separate chuck
• 118-degree standard point angle with web thinning reduces entry thrust on tough materials
• High speed steel construction with oxide finish resists heat buildup during general-purpose machining
• 7.875-inch spiral flute length supports chip evacuation in deep-hole applications
• Right-hand cut, regular spiral suitable for most drilling machines and CNC setups

Compatibility

Designed for use in drill presses, lathes, and milling machines equipped with a Morse Taper 3 (3MT) spindle socket. Fits any machine spindle or drill sleeve conforming to ANSI 3MT taper specifications.

Installation Notes

A licensed machinist or trained toolroom operator should install and operate this bit. Before mounting, power down and lock out the machine following applicable OSHA lockout/tagout procedures. Clean the taper shank and spindle bore of chips and oil before seating to ensure full contact and prevent shank slippage. A proper drift key should be used to eject the bit from the spindle — do not strike the spindle housing to remove the bit.
