Value Collection 01378199 Drill Bit Size 19 Cobalt 135 Deg

Product Description

The VALUE COLLECTION 01378199 is a screw machine length drill bit designed for high-speed, short-clearance drilling in metal fabrication, machining, and general mechanical work. Built from cobalt steel with a straw finish, this bit handles harder workpiece materials that would quickly wear down standard HSS tooling. The 135-degree split point self-centers on contact, reducing the need for a center punch and minimizing walking on smooth or curved surfaces. At 2.125 inches overall length, the stubby profile provides rigidity in drill presses and hand drills alike, making it a go-to choice for machinists, tool-and-die workers, and maintenance mechanics.

This bit is sized to wire gauge Number 19, with a decimal diameter of 0.1660 inches, placing it in the 0.1500 to 0.2000 inch drill bit size range. It is well suited for drilling clearance and tap holes in stainless steel, hardened alloys, and other tough materials where standard jobber-length bits lack the durability to perform consistently. The straight shank is compatible with standard drill chucks and collet holders used in both bench and floor-standing drill presses.

Key Features

• Cobalt steel construction for extended tool life in hard and abrasive materials
• 135-degree split point for self-centering and reduced thrust on entry
• Screw machine length (2.125 inches OAL) for added rigidity and control in tight setups
• Right-hand cutting direction for standard drill press and hand drill use
• Regular spiral with 2 flutes for efficient chip evacuation
• Straight shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-style replacement or direct addition for standard straight-shank drill chucks accepting bits in the 0.1500 to 0.2000 inch diameter range, including common 3-jaw drill press and hand drill chucks.

Installation Notes

Installation and use of drill bits should be performed by qualified machinists or mechanics familiar with cutting tool safety. Always power down and de-energize the drill press or driving tool before changing bits. Secure the workpiece firmly before drilling and use appropriate cutting fluid or coolant where required by the material, noting this bit does not support coolant-through operation. Inspect the bit for chips, cracks, or excessive wear before each use and replace if the cutting edges are compromised.
