Value Collection 01198480 Cobalt Jobber Drill Bit No. 48

Product Description

The VALUE COLLECTION 01198480 is a cobalt jobber-length drill bit sized to wire gauge No. 48, with a decimal diameter of 0.076 inches. It features a 135-degree split-point tip, which reduces walking on contact and allows drilling to begin without a center punch on most flat surfaces. The two-flute, regular-spiral design moves chips efficiently out of the hole. Cobalt construction gives this bit the hardness and heat resistance needed for demanding applications where high-speed steel bits fall short. Overall length is 2 inches with a 1-inch flute length. The straight cylindrical shank fits standard drill chucks without modification.

This bit is intended for drilling stainless steel, hardened materials, and other tough alloys that generate high cutting temperatures. It suits machinists, maintenance mechanics, fabricators, and tool-and-die work where precision small-diameter holes are required. The No. 48 wire gauge size is commonly used for tapping and clearance holes in fine-thread fastener work. The straw finish indicates the cobalt alloy has been heat-treated but left uncoated beyond that process, keeping the diameter accurate to spec.

Key Features

• Cobalt alloy construction for heat resistance when drilling stainless steel and hardened materials
• 135-degree split-point tip reduces bit walking and lowers thrust required at entry
• Regular two-flute spiral for consistent chip evacuation in deep holes
• No. 48 wire gauge size at 0.076 inches decimal diameter for fine-thread tap and clearance hole work
• Straight cylindrical shank fits standard three-jaw drill chucks
• Heavy-duty grade rated for demanding production and maintenance drilling cycles

Compatibility

Designed as a standard jobber-length drill bit for use in benchtop drill presses, hand drills, and CNC drilling setups accepting a straight cylindrical shank in the 0.0500 to 0.1000 inch diameter range.

Installation Notes

Install this bit in a clean, properly tightened chuck to prevent slippage at the shank during high-torque cuts in hard materials. Use appropriate cutting fluid or coolant when drilling stainless steel to extend bit life and maintain hole tolerance. Secure the workpiece firmly before drilling to prevent rotation or movement. Inspect the split point for chipping before each use; a damaged tip will produce oversized, off-center holes.
