Precision Twist Drill 6001148 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6001148 is a taper shank drill bit engineered for general-purpose drilling in metal, steel, and similar materials. Built from high speed steel with an oxide finish, it delivers reliable performance in production and maintenance machining environments. The bit carries a 3MT (Morse Taper 3) shank for direct mounting in taper-socket spindles on drill presses, lathes, and machining centers. At 0.9688 inches (31/32 inch) in diameter with an 11-inch overall length and a 118-degree standard point angle, it is sized for larger-diameter through-holes where a straight-shank bit would not provide adequate rigidity or torque transfer.

This bit is suited for use on vertical and radial drill presses, turret lathes, and manual machining centers in job shop, maintenance, and light industrial settings. The 6.375-inch spiral flute length gives adequate chip clearance for moderate-depth holes in ferrous and non-ferrous stock. Right-hand cutting direction and regular spiral geometry make it compatible with conventional spindle rotation on standard shop equipment. The web-thinned point reduces thrust requirements and improves centering on entry, which is useful when drilling larger-diameter holes without a pilot bore.

Key Features

• 0.9688 inch (31/32 inch) diameter for close-tolerance large-bore drilling
• 3MT Morse Taper shank mounts directly in taper-socket spindles without a chuck
• 118-degree standard point angle with web thinning for reduced entry thrust
• High speed steel construction with oxide finish for heat and wear resistance
• 6.375-inch flute length supports chip evacuation in deeper cuts
• Right-hand spiral flute, ANSI standard geometry, general-purpose performance rating

Compatibility

Designed for use in drill press, lathe, or machining center spindles fitted with a Morse Taper 3 socket. Suitable as a general-purpose replacement or addition for shops requiring 31/32-inch taper shank capacity.

Installation Notes

Installation is performed by machinists or toolroom personnel. Ensure the spindle socket and taper shank are clean and free of chips or burrs before seating; a contaminated taper will not seat fully and may cause runout or ejection under load. Secure the bit using the appropriate drift and draw bar method per the machine tool manufacturer specifications. Disengage power and bring the spindle to a full stop before inserting or removing the bit.
