Value Collection 01569276 Taper Shank Drill Bit 40mm 4MT

Product Description

The VALUE COLLECTION 01569276 is a taper shank drill bit designed for heavy-duty drilling in metal, steel, and similar materials. Built from high-speed steel with an oxide finish, this bit measures 40 mm (1.5748 inches) in diameter and seats into a 4MT (Morse Taper 4) spindle. The 118-degree standard point with web thinning reduces walking and cutting resistance at entry. A 200 mm (7.874 inches) spiral flute channel evacuates chips efficiently during right-hand cutting operations. Overall length is 349 mm (13.74 inches). This bit is suited for general-purpose production and maintenance drilling where a rigid, high-torque spindle drive is available.

This drill bit is intended for use in drill presses, milling machines, lathes, and other machine tools equipped with a 4MT taper socket. It handles general-purpose applications including through-hole and blind-hole drilling in ferrous metals and mild alloys. The regular spiral flute geometry performs well at standard cutting speeds. Coolant-through capability is not included, so external flood or mist coolant is recommended when drilling at depth or in harder workpiece materials to manage heat and tool life.

Key Features

• 40 mm diameter with 1.5748 inch decimal equivalent for cross-reference
• 4MT (Morse Taper 4) shank for secure, self-holding spindle engagement
• 118-degree standard point angle with web thinning for reduced thrust and cleaner entry
• High-speed steel construction with oxide finish for corrosion resistance and lubricity
• 200 mm (7.874 inches) spiral flute length for efficient chip evacuation
• Right-hand cutting, regular spiral — compatible with standard machine tool setups

Compatibility

Designed for use in machine tools equipped with a 4MT (Morse Taper 4) spindle socket, including drill presses, lathes, and milling machines configured for large-diameter taper shank tooling.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom professional. Power down and lock out the machine spindle before seating or removing the taper shank. Clean the taper socket and shank of chips, oil, and burrs before insertion to ensure full contact and prevent slipping under load. Do not use this bit in handheld power drills — a rigid machine spindle is required for safe operation at this diameter.
