Value Collection SC0850162 Hss Morse Taper Core Drill 1-31/32 in

Product Description

The VALUE COLLECTION SC0850162 is a high-speed steel Morse taper core drill designed for large-diameter hole drilling in metal fabrication, toolroom, and industrial maintenance applications. The 1-31/32 inch diameter cutting head features four flutes for efficient chip evacuation and a right-hand spiral cutting direction. With an overall length of 17-3/8 inches and a flute length of 10-3/8 inches, this drill reaches deep into workpieces where standard twist drills fall short. The 5MT shank provides positive drive in compatible Morse taper spindles and tailstocks. An oxide coating helps reduce friction and resist wear under demanding cutting conditions.

This core drill is suited for enlarging existing holes in ferrous and non-ferrous metals in job shop, maintenance, and production environments. The 4-flute design improves surface finish and stability compared to 2-flute alternatives, making it a practical choice for machinists and toolroom technicians who need consistent results on pre-drilled or pilot-bored workpieces. The 5MT shank fits standard Morse taper drill press quills and lathe tailstocks that accept No. 5 tooling.

Key Features

• 1-31/32 inch (1.9688 inch decimal) cutting diameter for large-bore applications
• 4-flute geometry promotes chip clearance and improved hole finish
• High-speed steel construction withstands elevated cutting temperatures
• 5MT Morse taper shank for secure, self-centering spindle engagement
• Oxide coating reduces surface friction and extends tool life
• 118-degree included angle suits general-purpose drilling in common metals
• Right-hand spiral and right-hand cutting direction for standard drill press and lathe use

Compatibility

Designed for use in drill presses, lathes, and milling machines equipped with a No. 5 Morse taper (5MT) spindle or tailstock. Functions as a core drill for enlarging pre-existing holes rather than drilling from solid stock.

Installation Notes

Installation and operation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before seating or removing the Morse taper shank. Clean both the tool shank and the spindle socket of chips and oil before insertion to ensure full taper contact. Core drills require a pilot hole or pre-bored starting point and should not be used to drill from solid material.
