Value Collection 01541135 Taper Shank Drill Bit 4MT Hss

Product Description

The VALUE COLLECTION 01541135 is a taper shank drill bit designed for heavy-duty drilling applications in metal fabrication, machining, and industrial maintenance work. Built from high-speed steel with an oxide finish, this bit measures 1-13/64 inches (1.2031 inches decimal) in diameter and is sized for a 4MT (Morse Taper 4) shank, making it compatible with drill presses and milling machines equipped with a matching taper socket. The 118-degree standard point angle and web-thinned geometry reduce walking and improve penetration on flat and curved stock. At 13-1/8 inches overall length with a 7-1/2 inch spiral flute, it handles deep-hole operations that shorter jobber-length bits cannot reach.

This bit is suited for general-purpose right-hand cutting in ferrous and non-ferrous metals, plastics, and composite materials. Typical install scenarios include production drilling on floor-standing drill presses, radial arm drills, and horizontal boring mills that accept 4MT tooling. Machinists, tool-and-die makers, and industrial maintenance technicians are the primary users. The oxide finish provides a modest level of lubricity and corrosion resistance for shop environments.

Key Features

• 1-13/64 inch diameter (1.2031 inches decimal) for large-bore hole making
• 4MT taper shank for self-holding fit in standard Morse Taper 4 spindles
• High-speed steel construction rated for general-purpose cutting in metal and plastic
• 118-degree standard point angle with web-thinned tip reduces thrust and improves centering
• 7-1/2 inch spiral flute length supports deep-hole drilling with efficient chip evacuation
• Right-hand cutting direction, regular spiral, oxide finish — no coolant-through feature

Compatibility

Designed as an OEM-style replacement or direct-fit bit for drill presses, radial drills, and boring mills fitted with a Morse Taper 4 spindle socket.

Installation Notes

Installation and removal of taper shank tooling should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine before seating or drifting the bit. Use the correct MT4 drift key and drift slot to remove the bit — never strike the bit directly. Verify spindle taper cleanliness and alignment before engaging the taper to prevent fretting and premature wear.
