Value Collection 01198597 Cobalt Jobber Drill Bit No. 59

Product Description

The VALUE COLLECTION 01198597 is a cobalt jobber-length drill bit sized to wire gauge No. 59 (0.0410 inches) and designed for drilling stainless steel, hardened alloys, and other tough ferrous and non-ferrous materials. The 135-degree split point reduces walking on entry and lowers thrust requirements, making it practical for hand-held and drill-press use in tight applications. The regular spiral flute efficiently clears chips during through-hole drilling. Overall length is 1.625 inches with a flute length of 0.6875 inches. The straw finish indicates the cobalt alloy composition and provides mild heat resistance suited to heavy-duty cutting cycles. Installed by machinists, maintenance techs, and fabricators who need consistent, small-diameter hole performance in demanding base materials.

This bit is intended for drilling stainless steel, hardened steel, and similarly difficult workpiece materials where high-speed steel bits lose edge life prematurely. The straight cylindrical shank fits standard drill chucks without adapters. Its compact 1.625-inch overall length suits bench-top drill presses, hand drills, and CNC setup work where a short, rigid tool is preferred. The right-hand cutting direction is compatible with conventional clockwise-rotating spindles found on the vast majority of drill press and hand-drill equipment in the trade.

Key Features

• Cobalt construction for extended edge life in stainless steel and hardened materials
• 135-degree split point reduces drill walk and lowers feed pressure at entry
• Regular spiral flute promotes efficient chip evacuation during through-hole drilling
• Right-hand cutting direction for use with standard clockwise-rotating equipment
• Straight cylindrical shank at 0.0410 inches fits standard chucks without adapters
• Heavy-duty grade rated for demanding production and maintenance drilling cycles

Compatibility

Designed for use in standard drill chucks accepting straight cylindrical shanks; sized for wire gauge No. 59 applications in the 0.0000 to 0.0500 inch decimal inch drill bit size range. Primary workpiece materials listed by the manufacturer are stainless steel and hardened materials.

Installation Notes

Secure the shank fully in a properly sized drill chuck before operation and verify chuck key is removed before starting the spindle. Power down and de-energize all equipment before changing bits. Use appropriate cutting fluid or coolant when drilling stainless steel or hardened alloys to preserve edge life and prevent work hardening. Dispose of worn bits in accordance with shop safety practices for metal swarf and small tooling.
