Value Collection 01541366 Taper Shank Drill Bit 1-9/16 in 4MT

Product Description

The VALUE COLLECTION 01541366 is a taper shank drill bit designed for heavy-duty drilling in metal, steel, and similar materials. It accepts a 4 Morse Taper (4MT) shank, making it compatible with taper-equipped drill presses, lathes, and milling machines commonly found in machine shops and fabrication environments. The cutting end features a 118-degree standard point with web thinning for improved penetration and reduced thrust. At 1-9/16 inches (1.5625 inches decimal) in diameter with a 13-3/4 inch overall length, this bit handles large-diameter through-holes and deep boring applications. It is ground from high-speed steel (HSS) and finished with an oxide coating that provides light corrosion resistance and reduces friction at the cutting edge.

This drill bit is intended for general-purpose machining work in industrial and trade settings. Typical applications include structural fabrication, toolroom work, and production drilling where a taper shank machine setup is already in place. The right-hand cutting direction and regular spiral flute geometry suit standard spindle rotation on floor-standing drill presses and manual lathes. The 7-7/8 inch flute length supports chip evacuation during deep-hole drilling passes. It is not designed for portable hand-drill use — a 4MT taper socket is required for proper seating and concentricity.

Key Features

• 1-9/16 inch (1.5625 inch) diameter with 4 Morse Taper shank for rigid machine tool mounting
• 118-degree standard point angle with web thinning to reduce entry thrust
• High-speed steel construction for general-purpose metal drilling
• Oxide finish provides light corrosion resistance and reduces heat buildup at the cutting face
• 7-7/8 inch spiral flute length promotes chip clearance in deeper cuts
• Right-hand cut, regular spiral — compatible with standard machine spindle rotation

Compatibility

Designed for use in machine tools equipped with a 4 Morse Taper socket, including floor-standing drill presses, engine lathes, and milling machine quills configured for 4MT tooling. A 4MT drill chuck or direct taper socket is required for installation.

Installation Notes

Installation requires a clean, dry 4MT taper socket — debris or oil in the socket will prevent proper seating and can cause the bit to spin or pull free under load. Power down and lock out the machine spindle before seating or removing the bit. Drive the shank firmly into the taper socket using a drift key through the spindle slot to release when changing tools. Consult the machine tool manufacturer guidelines and applicable shop safety codes before operation.
