Value Collection 01344126 Cobalt Drill Bit 1-3/16 in

Product Description

The VALUE COLLECTION 01344126 is a reduced shank cobalt drill bit built for general-purpose drilling in tough materials including stainless steel, cast iron, and high-strength alloys. The bit measures 1-3/16 inches in diameter with a 1/2 inch reduced shank, allowing it to be chucked in standard 1/2 inch drill chucks despite its large cutting diameter. The 118 degree standard point angle provides a versatile geometry suited to a wide range of metals and hard plastics. A straw finish indicates heat treatment consistent with cobalt construction. Right-hand spiral flutes evacuate chips efficiently during through-hole and deep drilling operations. Weighing 0.91 pounds, this is a substantial bit intended for stationary drill press or magnetic drill use.

This drill bit is designed for trade and industrial applications where oversized holes are required in ferrous metals, stainless steel, or similarly hard materials. Typical installation scenarios include mechanical contractors drilling flanged connections, HVAC technicians enlarging panel knockouts in heavy-gauge enclosures, plumbers boring through structural members, and fabrication shops producing precision holes in plate stock. The 3 inch flute length supports a maximum drilling depth of 3 inches, making it suitable for most structural and sheet material thicknesses encountered in trade work.

Key Features

• 1-3/16 inch cutting diameter with 1/2 inch reduced shank for use in standard 1/2 inch chucks
• Cobalt tool material resists heat and wear when drilling hardened or abrasive metals
• 118 degree standard point angle for versatile general-purpose metal drilling
• Right-hand cut with regular spiral flutes for efficient chip evacuation
• 3 inch flute length with 6 inch overall length supports up to 3 inches of drilling depth
• Straw finish indicates cobalt heat treatment; no coolant-through feature

Compatibility

Designed as a general-purpose reduced shank drill bit compatible with any 1/2 inch capacity drill chuck on stationary drill presses, magnetic drills, or heavy-duty hand drills.

Installation Notes

This bit should be installed and operated by qualified tradespeople familiar with large-diameter metal drilling. Secure the workpiece firmly before drilling and use a drill press or magnetic base drill for holes of this diameter to maintain alignment and operator safety. Power down and lock out the machine before changing bits. Operating at appropriate RPM for the material and diameter is critical to bit life — consult a speeds and feeds chart for cobalt bits at 1-3/16 inch diameter.
