Value Collection 01541184 Taper Shank Drill Bit 4MT Hss

Product Description

The VALUE COLLECTION 01541184 is a taper shank drill bit designed for heavy-duty drilling in metal, cast iron, and similar materials. Built from high-speed steel with an oxide finish, it delivers consistent performance in general-purpose machining applications. The bit features a 1-9/32 inch (1.2813 inch decimal) diameter, a 118-degree standard point angle, and a web-thinned tip geometry that reduces thrust and improves chip clearing at entry. A right-hand spiral flute with a 7.25 inch flute length moves chips efficiently out of the hole. At 13.125 inches overall length, this bit is suited for work requiring extended reach or deep-hole drilling on drill presses and milling machines.

This taper shank drill bit fits machine tool spindles with a No. 4 Morse Taper (4MT) socket, making it compatible with drill presses, lathes, and milling machines equipped with a matching taper bore. It is a general-purpose cutting tool used in job shops, manufacturing facilities, and maintenance environments. Machinists and tool-and-die technicians typically reach for this size when drilling large-diameter through holes or stepped bores in ferrous and non-ferrous stock. Coolant-through capability is not available on this model, so surface speeds and feed rates should be managed to control heat buildup during extended cuts.

Key Features

• 1-9/32 inch diameter (1.2813 inch decimal) for large-bore drilling applications
• No. 4 Morse Taper shank for secure, self-holding fit in compatible spindles
• High-speed steel construction with oxide finish for wear resistance and corrosion protection
• 118-degree standard point angle with web-thinned geometry reduces entry thrust
• Right-hand regular spiral flute promotes efficient chip evacuation
• General-purpose tool performance suitable for ferrous and non-ferrous materials

Compatibility

Designed for use in drill press spindles, lathe tailstocks, and milling machine quills fitted with a No. 4 Morse Taper (4MT) socket. Verify spindle taper designation before installation.

Installation Notes

Installation and removal should be performed by a qualified machinist or tool operator. Power down and lock out the machine before inserting or removing the taper shank. Clean both the shank and the spindle taper bore with a lint-free cloth to remove oil and chips before seating; contaminants will reduce holding force and can cause runout. Use a drift key and mallet in the spindle drift slot to break the taper loose for removal — never pry against the flutes.
