Value Collection 01198431 Cobalt Jobber Drill Bit No. 43

Product Description

The VALUE COLLECTION 01198431 is a cobalt jobber-length drill bit sized to wire gauge No. 43, equivalent to 0.0890 inches in diameter. Built for heavy-duty drilling applications, it features a 135-degree split point that reduces walking and minimizes the need for a center punch on hard or slippery surfaces. The straw finish indicates the cobalt steel composition, which provides greater heat resistance than standard high-speed steel. At 2.25 inches overall length with a 1.25-inch flute length, this bit is suited for precision work in tight clearances. A right-hand, regular spiral flute evacuates chips efficiently during through-hole and blind-hole operations.

This drill bit is designed primarily for cutting stainless steel and other hardened or work-hardening materials where standard HSS tooling wears prematurely. Typical applications include HVAC bracket fabrication, plumbing rough-in through hard sheet metal, electrical panel work, and general maintenance drilling in ferrous and non-ferrous metals. The straight cylindrical shank seats securely in standard drill chucks without special collets. This bit is sold individually and is intended for use in hand drills, drill presses, and portable magnetic-base drills.

Key Features

• Cobalt steel construction for extended tool life in stainless steel and hardened materials
• 135-degree split point reduces thrust force and prevents bit walking on curved or slick surfaces
• Right-hand, regular spiral flute promotes efficient chip evacuation in both through and blind holes
• No coolant-through design — suitable for standard hand-tool and drill-press use without coolant infrastructure
• Straight cylindrical shank fits standard three-jaw drill chucks without adapters
• Heavy-duty grade rated for repeated use in demanding trade environments

Compatibility

Designed as a heavy-duty OEM-style replacement or stock bit for trade applications requiring a wire gauge No. 43 (0.0890 inch) diameter hole, compatible with any standard drill chuck accepting a straight shank of 0.0890 inches in diameter.

Installation Notes

This bit is installed and used by HVAC technicians, plumbers, electricians, and general maintenance tradespeople working with hand drills or drill presses. Secure the straight shank firmly in the chuck before operation and verify chuck key is removed prior to powering the tool. When drilling stainless steel or hardened materials, use a slow, steady feed rate with light cutting oil to extend bit life and prevent work hardening of the workpiece. Discontinue use if the bit shows signs of bluing beyond the straw finish, dulling, or point deformation.
