Value Collection 01370121 3/16 in Cobalt Drill Bit 135 Deg

Product Description

The VALUE COLLECTION 01370121 is a screw machine length cobalt drill bit designed for heavy-duty drilling in hard and abrasive materials. With a 3/16 inch diameter and a 135-degree split point, it starts on contact without a center punch and resists walking on curved or uneven surfaces. The cobalt construction provides heat resistance during high-speed drilling in stainless steel, cast iron, titanium, and other tough alloys. The right-hand, two-flute regular spiral design efficiently clears chips from the cut zone. At 2-3/16 inches overall length, this stub-style bit fits standard drill chucks and is sized for use in tight or confined spaces where a jobber-length bit will not reach or seat properly.

Screw machine length drill bits are standard tooling in machine shops, fabrication facilities, and maintenance environments where high cycle rates and hard materials are common. This bit is suited for use in drill presses, CNC machining centers, and hand-held power drills operating in metals that would quickly wear a standard high-speed steel bit. The shorter overall length reduces deflection and improves hole-location accuracy. Machinists, tool and die workers, and industrial maintenance technicians are the primary users of this bit profile.

Key Features

• Cobalt construction resists heat buildup in hard and abrasive metals
• 135-degree split point self-centers on contact, eliminating the need for a center punch
• Screw machine (stub) length at 2-3/16 inches overall reduces deflection and improves rigidity
• Right-hand cut with regular two-flute spiral for efficient chip evacuation
• Straight shank fits standard drill chucks without a reducer
• Heavy-duty grade rated for continuous use in demanding production environments

Compatibility

Designed as an OEM-style replacement or stock tooling for straight-shank drill chucks in drill presses, machining centers, and hand-held power drills requiring a 3/16 inch stub-length cobalt bit.

Installation Notes

Installation is performed by machinists and maintenance technicians familiar with rotating tooling. Secure the straight shank fully into the drill chuck and tighten with a chuck key before use. Inspect the cutting edges for chipping or wear before each use, and discard bits that show signs of cracking or excessive wear to avoid workpiece damage. Follow applicable shop safety procedures and machine guarding requirements when operating any rotary cutting tool.
