Value Collection SC0850146 Hss Morse Taper Core Drill 1-23/32 in

Product Description

The VALUE COLLECTION SC0850146 is a high-speed steel Morse taper core drill designed for enlarging existing holes to precise diameters in metal fabrication and machining applications. With a 1-23/32 inch cutting diameter and a 4-flute geometry, this drill produces cleaner hole walls and faster material removal than a standard 2-flute twist drill. The 5MT shank seats directly into compatible Morse taper spindles, eliminating the need for a separate chuck. An oxide coating reduces friction and provides light corrosion resistance during storage and use. At 17-1/8 inches overall length, this tool reaches deep setups where standard-length drills fall short.

This core drill is suited for machine shops, tool rooms, and industrial maintenance environments where holes are pre-drilled or cast and require finishing to a close tolerance. It is designed for use in drill presses, lathes, radial arm drills, and milling machines equipped with a No. 5 Morse taper spindle. Typical applications include enlarging pilot holes in steel, cast iron, and non-ferrous alloys. Right-hand spiral and right-hand cut geometry make it compatible with standard forward-rotation spindles.

Key Features

• 1-23/32 inch (1.7188 inch decimal) cutting diameter for precise hole sizing
• 4-flute design improves chip evacuation and hole surface finish versus 2-flute drills
• High-speed steel construction withstands the heat generated in production drilling
• No. 5 Morse taper shank for direct spindle mounting without a chuck
• Oxide finish reduces friction and provides storage-level corrosion protection
• 17-1/8 inch overall length with 10-1/8 inch flute length for deep-reach capability

Compatibility

Designed for use in drill presses, lathes, radial arm drills, and milling machines equipped with a No. 5 Morse taper (5MT) spindle socket. This tool is intended for enlarging pre-existing holes and is not designed as a spot or solid drilling tool from solid stock.

Installation Notes

Installation requires a machine spindle with a No. 5 Morse taper socket. Power down and lock out the machine before seating or removing the taper shank. Use a proper drift key through the spindle slot to eject the shank cleanly — never strike the drill body directly. Secure workpieces firmly with appropriate fixturing before operation to prevent rotation under cutting load.
