Precision Twist Drill 010313 Hss Cobalt Jobber Drill 13/64 in

Product Description

The PRECISION TWIST DRILL 010313 is a high-speed steel cobalt jobber drill designed for heavy-duty drilling in hard and abrasive materials. This type J straight-shank drill features a 13/64-inch tip diameter and an overall length of 3-5/8 inches, with a depth of cut reaching 4 inches. The cobalt content in the HSS matrix increases heat resistance and edge retention, making it suitable for sustained use in tough ferrous and non-ferrous metals. Licensed tradespeople and machining professionals reach for this drill when standard HSS bits fail to hold up under continuous load or elevated cutting temperatures.

This jobber-length drill is suited for general-purpose metal drilling in fabrication shops, maintenance and repair operations, and industrial service environments. The straight shank accepts standard three-jaw chucks on drill presses, cordless and corded hand drills, and milling machine spindles. Its heavy-duty construction is well matched to stainless steel, hardened alloys, cast iron, and other materials that generate significant heat during cutting. It is sold in individual pack quantity.

Key Features

• HSS cobalt construction for increased heat resistance and edge retention in hard materials
• 13/64-inch diameter tip for precise hole sizing
• 3-5/8-inch overall length with 4-inch depth of cut capability
• Type J heavy-duty straight shank compatible with standard chucks
• Jobber-length geometry balances rigidity and reach for general metalworking tasks

Compatibility

Designed as an OEM-style replacement and general-use drill bit compatible with any standard three-jaw drill chuck accepting straight-shank bits in the 13/64-inch size.

Installation Notes

Installation and operation should be performed by qualified machinists or trade professionals familiar with drill press and hand-drill safety practices. Secure the workpiece firmly before drilling and confirm the chuck is tightened on the full straight shank. Use appropriate cutting fluid when drilling hard or heat-sensitive metals to extend tool life. Wear proper eye protection and follow applicable shop safety standards during use.
