Value Collection 01198423 Cobalt Jobber Drill Bit No. 42

Product Description

The VALUE COLLECTION 01198423 is a cobalt jobber-length drill bit sized to wire gauge No. 42 (0.0935 inches decimal), designed for drilling into stainless steel, hardened materials, and other tough alloys that defeat standard high-speed steel tooling. The bit features a 135-degree split point that reduces walking and cuts with less axial thrust than a conventional 118-degree geometry. A straw finish indicates the heat treatment applied during manufacture. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling operations. This bit is a standard production tool used by machinists, maintenance technicians, and fabricators working with hard or abrasive stock.

The 01198423 is suited for light-duty drilling in metalworking, mechanical maintenance, and fabrication environments where a small-diameter, precision wire-gauge hole is required. Typical applications include pilot holes, tapping prep for small-thread fasteners, and instrumentation or sensor port drilling in stainless steel components. The 2.25-inch overall length and 1.25-inch flute length fit standard drill chucks and quick-change collet systems. It is appropriate for use in drill presses, CNC machines, and hand-held power drills with a stable workholding setup.

Key Features

• Cobalt construction provides heat resistance and hardness retention when cutting stainless steel and hardened materials
• 135-degree split point reduces thrust, minimizes bit walking, and improves hole entry accuracy
• Wire gauge No. 42 size at 0.0935 inches decimal for precise small-diameter hole applications
• Right-hand regular spiral flutes with 1.25-inch flute length for effective chip evacuation
• Straight cylindrical shank at 0.0935 inches diameter fits standard drill chucks without adapters
• Heavy-duty grade rating for demanding production and maintenance drilling tasks

Compatibility

Designed as a standard wire-gauge jobber drill bit compatible with any drill press, CNC machining center, or hand-held power drill equipped with a chuck capable of holding a 0.0935-inch straight shank.

Installation Notes

Secure the workpiece firmly in a vise or fixture before drilling to prevent movement and bit breakage at this small diameter. Use appropriate cutting fluid or coolant when drilling stainless steel to reduce heat buildup and extend bit life. Set spindle speed according to standard feeds-and-speeds references for the specific material and cobalt tooling diameter. Inspect the split point for chipping before each use, as small-diameter cobalt bits are susceptible to breakage if run at incorrect speeds or with excessive side load.
