Value Collection 01242205 Jobber Drill Bit 2.20mm Hss

Product Description

The VALUE COLLECTION 01242205 is a high-speed steel (HSS) jobber-length drill bit designed for general-purpose drilling in steel, cast iron, and similar ferrous materials. The 118-degree standard point angle provides a self-centering entry that suits a wide range of workpiece materials. An oxide coating reduces friction and provides moderate surface protection during drilling operations. At 2.25 inches overall length with a 1.27-inch flute length, this bit is sized for compact drilling tasks and fits standard drill chucks and rotary tools with a straight cylindrical shank. Two right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole operations. This bit is sold individually and is suited for use by machinists, maintenance technicians, electricians, and plumbers who need a reliable general-purpose metric drill bit in their kit.

This jobber drill bit is intended for light to medium-duty drilling in ferrous metals including steel and cast iron. Its 2.20 mm diameter (0.0866 inch decimal equivalent) fills a common metric sizing need in fabrication, HVAC bracket work, pipe fitting layout, and electrical panel work. The straight cylindrical shank fits into standard 3-jaw drill chucks on benchtop drill presses, hand drills, and magnetic base drills. Web-thinned geometry reduces thrust force at the cutting tip, making it practical for hand-held drilling applications where feed pressure must be controlled.

Key Features

• 2.20 mm (0.0866 inch) diameter for precise metric-sized holes in ferrous workpieces
• 118-degree standard point angle with web-thinned, tapered web geometry for reduced thrust
• High-speed steel construction rated for steel and cast iron applications
• Oxide coating reduces friction and provides basic corrosion resistance
• Regular right-hand spiral flutes for efficient chip evacuation
• Straight cylindrical shank fits standard 3-jaw drill chucks without adapters

Compatibility

Designed as a general-purpose metric jobber drill bit compatible with any standard 3-jaw drill chuck that accepts a 0.0886-inch diameter straight cylindrical shank, suitable for benchtop drill presses, hand drills, and rotary tool setups used in steel and cast iron applications.

Installation Notes

This bit is installed and operated by machinists, maintenance trades, and field technicians using standard drill chucks. Secure the shank fully in the chuck jaws before operation and confirm chuck key is removed before powering the drill. Use cutting fluid or cutting oil when drilling steel to extend bit life and maintain hole quality. Replace the bit if point geometry shows chipping or if the cutting edges show signs of heat discoloration indicating overheating.
