Value Collection 01198449 Cobalt Jobber Drill Bit No. 44

Product Description

The VALUE COLLECTION 01198449 is a cobalt jobber-length drill bit sized to wire gauge No. 44 (0.0860 inches decimal) with a 135-degree split point. Cobalt construction provides elevated heat resistance and edge retention compared to standard high-speed steel, making this bit well suited for tough interrupted cuts and abrasive materials. The split point geometry reduces walking on entry and lowers the thrust force needed to penetrate hard stock. At 2.125 inches overall length with a 1.125-inch flute length, this is a compact, rigid jobber format intended for precision hole work in tight access areas or on small-diameter workpieces.

This bit is designed for drilling stainless steel, hardened materials, and other ferrous alloys that generate high cutting heat. The regular spiral flute evacuates chips efficiently in two-flute configuration, reducing chip packing in deep or blind holes. Machinists, tool-and-die workers, maintenance technicians, and heavy-duty shop fabricators commonly reach for cobalt jobber bits at this diameter when stainless sheet, fastener holes, or small-bore pilot work is on the job. The straight cylindrical shank fits standard drill chucks and collets sized for 0.0860-inch shanks.

Key Features

• Cobalt construction for superior heat resistance and longer tool life in hard and abrasive materials
• 135-degree split point reduces bit walking and lowers required feed pressure on entry
• Regular spiral two-flute design promotes consistent chip evacuation
• Right-hand cutting direction compatible with standard drill press and hand-drill rotation
• Straight cylindrical shank for universal chuck and collet compatibility
• Heavy-duty grade rated for stainless steel and hardened workpiece materials

Compatibility

Designed as an OEM-style jobber drill bit replacement for applications requiring a wire gauge No. 44 (0.0860-inch decimal) hole in stainless steel, hardened metals, or similarly demanding ferrous materials.

Installation Notes

Cobalt drill bits should be installed in a properly sized drill chuck or collet with shank fully seated before tightening. Use appropriate cutting fluid or coolant when drilling stainless steel or hardened materials to extend bit life and prevent work hardening at the cut. Machine spindle speed and feed rate should be set per standard cobalt-bit guidelines for the workpiece material and diameter. Inspect the cutting edges before each use and replace the bit if chipping or edge rollover is observed.
