Value Collection 13-184 Cobalt Jobber Drill Bit 0.1935 in

Product Description

The VALUE COLLECTION 13-184 is a cobalt jobber-length drill bit designed for general-purpose drilling in demanding materials. Built to Series 13 standards, it features a 0.1935 inch (Wire Size #10) diameter with a 135-degree split-point geometry that reduces walking and decreases the thrust needed to start a hole. The regular spiral flutes evacuate chips efficiently, and the straw finish indicates heat treatment consistent with cobalt-grade tooling. Right-hand cutting with a straight cylindrical shank, this bit is suited for machinists, pipefitters, plumbers, and HVAC technicians who regularly drill into stainless steel or hardened materials.

This drill bit is intended for use in stainless steel and hardened materials where standard high-speed steel bits lose their edge prematurely. The double-margin construction maintains accurate hole geometry through the full cut. With a flute length of 2.4375 inches and an overall length of 3.625 inches, it fits standard drill chucks and magnetic drill presses used in field and shop environments. Applicable across residential and light commercial trade work wherever precise, clean holes are required in difficult substrates.

Key Features

• Cobalt construction handles stainless steel and hardened materials that wear out standard HSS bits
• 135-degree split point reduces bit walking and lowers required drilling thrust
• Double-margin design maintains hole accuracy and roundness through the full cutting depth
• Regular spiral flutes with right-hand cutting for efficient chip removal
• Straight cylindrical shank fits standard keyed and keyless drill chucks without adapters
• Series 13 jobber length provides a flute-to-diameter ratio of 13xD for balanced reach and rigidity

Compatibility

Designed as a general-purpose jobber drill bit compatible with any standard drill chuck accepting a 0.1935 inch straight shank, including handheld drills, drill presses, and magnetic base drills used in trade applications.

Installation Notes

A licensed machinist or qualified trade professional should secure the workpiece firmly before drilling to prevent rotation or shifting. Use appropriate cutting fluid or coolant when drilling stainless steel to reduce heat buildup and extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or dullness is detected, as a degraded cobalt bit can seize in stainless steel. Follow applicable workplace safety standards and wear proper eye protection when operating any rotary cutting tool.
