Value Collection SC0840114 Hss Morse Taper Core Drill

Product Description

The VALUE COLLECTION SC0840114 is a high-speed steel Morse taper core drill designed for enlarging and finishing existing holes in metal workpieces. The 1-7/32 inch (1.2188 inch decimal) cutting diameter and 4-flute geometry deliver smooth, efficient material removal with reduced chatter compared to standard twist drills. At 13-1/8 inches overall length with a 7-1/2 inch flute length, this drill provides the reach needed for deeper bores. The oxide coating adds surface hardness and mild lubricity to extend tool life in production drilling environments. It is installed and used by machinists, tool and die makers, and maintenance mechanics working on drill presses, lathes, and milling machines.

This core drill is suited for enlarging cored, punched, or pre-drilled holes in ferrous and non-ferrous metals in both job-shop and production settings. The 4MT (No. 4 Morse Taper) shank seats directly into compatible machine spindles without an adapter in most heavy-duty drill press and lathe applications. Right-hand spiral and right-hand cutting direction are standard for conventional clockwise spindle rotation. It is a practical choice for maintenance shops and manufacturing floors where accurate hole sizing without full-diameter drilling is required.

Key Features

• 1-7/32 inch (1.2188 inch) cutting diameter for precise hole enlargement
• 4-flute design improves cutting stability and surface finish over 2-flute alternatives
• No. 4 Morse Taper (4MT) shank for direct spindle mounting on compatible machines
• High-speed steel construction handles a broad range of metals
• Oxide finish provides mild corrosion resistance and reduces friction during cutting
• Right-hand cut and right-hand spiral for standard clockwise spindle operation
• 13-1/8 inch overall length with 7-1/2 inch flute length for deep-reach applications

Compatibility

Designed for use in drill presses, lathes, and milling machines equipped with a No. 4 Morse Taper spindle socket. Core drills of this type are used to enlarge pre-existing holes and are not intended to drill from solid stock.

Installation Notes

Installation should be performed by a qualified machinist or maintenance mechanic. Power down and lock out the machine spindle before seating or removing the taper shank. Ensure the 4MT shank and spindle socket are clean and free of chips or burrs before insertion to achieve full taper engagement. Use appropriate cutting fluid for the workpiece material to prolong tool life and maintain surface finish.
