Value Collection 01378462 Size 46 Cobalt Drill Bit

Product Description

The VALUE COLLECTION 01378462 is a screw machine length drill bit designed for high-speed, close-tolerance drilling in metal and other tough materials. Built from cobalt high-speed steel, it handles elevated heat without losing hardness, making it well suited for stainless steel, cast iron, and hardened alloys. The 135-degree split point starts on contact without a center punch, reducing walking on hard surfaces. At 1.75 inches overall length, this stub-length geometry provides added rigidity and reduced deflection in short drilling applications. It is sized to wire gauge No. 46, equivalent to 0.0810 inch diameter. Trade professionals and machinists reach for this bit when precision hole sizing and drill life matter more than cost per bit.

This bit is used in production machining, maintenance and repair, and sheet metal work where short, stiff drill geometry improves accuracy. The straight shank fits standard drill chucks and quick-change holders. Its compact overall length is well suited to drill presses, CNC machining centers, and hand drills operating in confined spaces. The heavy-duty cobalt grade holds up in interrupted cuts and abrasive materials that would wear down standard high-speed steel bits quickly.

Key Features

• Cobalt construction resists heat buildup during drilling in hard and abrasive materials
• 135-degree split point starts on contact and reduces drill walking without center punching
• Screw machine (stub) length at 1.75 inches overall provides added rigidity and reduces deflection
• 0.75 inch flute length with regular spiral geometry for efficient chip evacuation
• Right-hand cutting direction compatible with standard drill chucks and spindles
• Straight shank fits common drill chucks and quick-change tooling systems

Compatibility

Designed as an OEM-style replacement or standard shop consumable for any application requiring a wire gauge No. 46 diameter hole; fits standard straight-shank drill chucks across drill presses, CNC machining centers, and portable hand drills.

Installation Notes

Installation is performed by machinists, maintenance technicians, and tool-and-die professionals. Secure the straight shank fully into the drill chuck before operation and verify runout before drilling into finished workpieces. Always power down and lock out the machine spindle before changing drill bits. Do not exceed the recommended RPM range for the workpiece material and bit diameter to avoid overheating the cobalt substrate.
