Value Collection SC0850158 Morse Taper Core Drill

Product Description

The VALUE COLLECTION SC0850158 is a high-speed steel Morse taper core drill designed for heavy-duty hole-making in metal fabrication and machining applications. With a 1-29/32 inch (1.9063 inch decimal) cutting diameter and an overall length of 17-3/8 inches, this drill handles deep-hole boring where standard twist drills fall short. The 5MT Morse taper shank seats directly into compatible drill press spindles or lathe tailstocks without an adapter chuck. An oxide coating provides corrosion resistance and mild lubricity during cutting. Licensed machinists, tool-and-die makers, and industrial maintenance technicians are the primary users.

This core drill is suited for enlarging pre-existing holes in ferrous and non-ferrous metals, castings, and similar materials in both production shop and maintenance-repair environments. The 4-flute design distributes cutting load evenly, improves hole finish, and provides better chip evacuation than a standard 2-flute drill when operating on a through-bore or pre-drilled pilot hole. The 10-3/8 inch flute length accommodates significant depth of cut in a single pass. Right-hand spiral and right-hand cutting direction are standard for conventional spindle rotation.

Key Features

• 1-29/32 inch (1.9063 inch) cutting diameter for precise, consistent hole sizing
• 5MT Morse taper shank for direct-mount in compatible drill press or lathe spindles
• 4 flutes for improved finish quality and chip evacuation versus 2-flute designs
• 10-3/8 inch flute length enables deep-hole applications in a single pass
• High-speed steel construction withstands elevated cutting temperatures
• Oxide finish provides corrosion resistance and mild lubricity
• 118-degree included angle is the standard geometry for general-purpose metal drilling

Compatibility

Designed for use in drill presses, lathes, and radial arm drills equipped with a No. 5 Morse taper (5MT) spindle socket. Core drills require a pre-drilled or cored pilot hole and are not intended for drilling from solid stock.

Installation Notes

Installation is performed by qualified machinists or maintenance technicians. Power down and lock out the machine before seating or removing the taper shank. Clean the spindle bore and taper shank with a lint-free cloth before insertion to ensure full taper contact and prevent fretting. Use a taper drift through the spindle drift slot to remove the tool — never strike the shank directly with a hammer.
