Value Collection 01378363 Cobalt Drill Bit Size 36

Product Description

The VALUE COLLECTION 01378363 is a cobalt screw machine length drill bit designed for heavy-duty drilling applications in metalworking and fabrication environments. Built to wire gauge size 36, it measures 0.1065 inches in decimal diameter and delivers a 135-degree split point for fast, self-centering starts on ferrous and non-ferrous materials. The screw machine length format — shorter overall than a jobber bit — provides added rigidity and reduced deflection, making it well suited for production drilling, CNC setups, and drill press work. A right-hand spiral with a regular flute design clears chips efficiently at standard feed rates.

This bit fits production and job shop environments where tight hole tolerances and consistent performance are required across repeated operations. The 135-degree split point eliminates the need for a center punch on most flat surfaces and reduces thrust load at the spindle. Typical users include machinists, tool-and-die makers, and metalworking fabricators running manual drill presses, mill-drill machines, or CNC machining centers. The cobalt construction handles elevated cutting temperatures better than standard high-speed steel, making it a practical choice when drilling harder alloys or stainless steel grades.

Key Features

• Cobalt tool material — resists heat and wear during high-speed or dry cutting in hard materials
• 135-degree split point for self-centering entry and reduced thrust load
• Screw machine length for increased rigidity and minimal deflection
• Right-hand cutting direction with regular spiral flutes for efficient chip evacuation
• Straight shank compatible with standard drill chucks and collets
• Heavy-duty grade construction rated for production drilling cycles

Compatibility

Designed as a standard screw machine length drill bit in wire gauge size 36, compatible with any drill chuck or collet accepting a straight-shank bit in the 0.1000 to 0.1500 inch decimal diameter range.

Installation Notes

Installation is performed by machinists or metalworking tradespeople using a drill press, mill-drill, or CNC machining center. Secure the straight shank firmly in a properly sized chuck or collet before operation. Always power down and de-energize the machine spindle before inserting or removing bits. Confirm work piece is clamped securely to prevent movement during drilling, and apply appropriate cutting fluid when drilling hard alloys to extend tool life.
