Value Collection 01664820 Taper Shank Drill Bit 1-1/2 in 4MT

Product Description

The VALUE COLLECTION 01664820 is a taper shank drill bit designed for heavy-duty drilling in metal, steel, and similar materials. It features a 1-1/2 inch diameter cutting edge, a 4MT (Morse Taper 4) shank for secure seating in compatible spindles and drill presses, and a 118-degree standard point angle suited to general-purpose work. The high-speed steel construction with an oxide finish provides wear resistance across a broad range of drilling applications. This bit is a right-hand cut with a regular spiral flute and web-thinned point to reduce feed pressure and improve chip evacuation. Machinists and tool-room technicians are the primary users.

This drill bit is intended for general-purpose drilling operations in machine shop, fabrication, and industrial maintenance environments. The 4MT taper shank seats directly into drill press spindles, milling machine quills, or lathe tailstocks equipped with a Morse Taper 4 socket. With an 18-inch overall length and a 12-inch flute length, it provides extended reach for deep-hole applications where shorter jobber-length bits cannot reach. No coolant-through capability is present, so external cutting fluid application is the standard practice for prolonged cuts.

Key Features

• 1-1/2 inch diameter, right-hand cut for standard drilling operations
• 4MT (Morse Taper 4) shank for positive, self-holding fit in compatible spindles
• 118-degree standard point angle with web-thinned tip to reduce thrust and improve chip clearing
• High-speed steel construction with oxide finish for heat and wear resistance
• Regular spiral flute, 12 inches in length, for efficient chip evacuation
• 18-inch overall length for extended reach in deep-hole applications

Compatibility

Designed for use in drill presses, milling machines, and lathe tailstocks fitted with a Morse Taper 4 socket. Suited for general-purpose drilling in ferrous and non-ferrous metals in Series 502 tooling configurations.

Installation Notes

Installation is performed by machinists or qualified tool operators. Before mounting, power down and lock out the machine per applicable OSHA lockout/tagout procedures. Clean the taper shank and spindle socket thoroughly before seating to ensure full contact and prevent slippage. Apply cutting fluid externally when drilling steel or other hard materials to extend bit life and manage heat buildup.
