Precision Twist Drill 6001020 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6001020 is a taper shank drill bit engineered for general-purpose drilling in metal, cast iron, and similar materials. It carries a 2MT (Morse Taper 2) shank for direct mounting in compatible drill presses, lathes, and milling machines without a separate chuck. The bit is ground from high speed steel with an oxide finish that provides light lubricity and corrosion resistance. At 0.689 inches (17.50 mm) in diameter and 9 inches overall length, it covers medium-to-large hole applications where rigidity and accurate sizing are required. The 118-degree standard point angle suits a broad range of ferrous and non-ferrous workpieces.

This drill bit is suited for machine shop, maintenance, and fabrication environments where a Morse taper spindle is available. Typical applications include drilling through structural steel, plate, and similar stock on a drill press or lathe. The right-hand spiral flute and web-thinned point reduce thrust and improve chip evacuation, making it practical for production and job-shop use. It conforms to DIN 345 standards and belongs to the Series 5ATS line. No coolant-through capability is present, so conventional flood or mist cooling at the cutting zone is recommended for extended runs.

Key Features

• 2MT Morse taper shank for secure, direct mounting in taper-spindle machines
• High speed steel construction with oxide finish for general-purpose durability
• 118-degree standard point angle with web-thinned geometry to reduce entry thrust
• Right-hand regular spiral flute, 5.09 inches flute length for efficient chip clearing
• Conforms to DIN 345 standards
• No coolant-through passages — use external cooling for heat management

Compatibility

Designed for use in drill presses, lathes, and milling machines equipped with a No. 2 Morse Taper (2MT) spindle or tailstock. A 2MT drill sleeve or socket may be used to adapt to larger taper spindles.

Installation Notes

Installation requires a machine spindle or tailstock with a No. 2 Morse Taper bore; ensure the taper surfaces are clean and free of burrs before seating the shank. Power down and lock out the machine before inserting or removing the bit. Use a drift key through the spindle slot to eject the bit — never strike the shank directly. A licensed machinist or qualified tradesperson should verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before drilling.
