Value Collection 01531136 Taper Shank Drill Bit 3MT Hss

Product Description

The VALUE COLLECTION 01531136 is a taper shank drill bit engineered for heavy-duty drilling applications in metal fabrication, machining, and general shop work. Manufactured from high-speed steel with an oxide finish, this bit measures 1-13/64 inches (1.2031 inches decimal) in diameter and seats into a Morse taper No. 3 spindle. The 118-degree standard point geometry with web thinning reduces thrust during entry and suits a broad range of ferrous and non-ferrous materials. Machinists, toolroom operators, and skilled tradespeople working with drill presses or milling machines are the primary users of this bit.

This taper shank drill bit is suited for use in drill presses, lathes, and milling machine quills equipped with a No. 3 Morse taper socket. The right-hand spiral flute with a regular spiral type evacuates chips efficiently during deep-hole drilling in steel, cast iron, aluminum, and similar materials. With a 7.5-inch flute length and 12.125-inch overall length, the bit reaches into deeper workpieces where straight-shank bits cannot provide adequate reach or rigidity. It is rated for general-purpose tool performance across a wide range of shop and production environments.

Key Features

• 1-13/64 inch diameter (1.2031 inches decimal) for precise hole sizing
• No. 3 Morse taper shank for positive, repeatable seating in compatible spindles
• 118-degree standard point with web thinning to reduce drill thrust and walking
• High-speed steel construction withstands heat generated in ferrous metal drilling
• Oxide finish provides mild lubricity and corrosion resistance during storage
• Right-hand cut with regular spiral flute for efficient chip evacuation
• No coolant-through feature — suitable for external coolant or dry drilling setups

Compatibility

Designed for use in any drill press, lathe tailstock, or milling machine spindle fitted with a No. 3 Morse taper socket.

Installation Notes

Installation and removal of taper shank tooling should be performed by a qualified machinist or toolroom technician. Power must be fully disconnected and the spindle brought to a complete stop before inserting or drifting out the bit. Use a proper Morse taper drift and a dead-blow mallet to seat and remove the shank cleanly — do not use a standard hammer directly on the tool. Confirm the taper socket is free of chips, burrs, and oil before seating to ensure full contact and prevent slippage under load.
