YG-1 D2GP185008 Jobber Drill Bit 1/8 Inch Tin Hss

Product Description

The YG-1 D2GP185008 is a jobber-length drill bit designed for general-purpose drilling in steel and similar ferrous materials. It is manufactured from high speed steel (HSS) with a titanium nitride (TiN) coating that extends cutting life by reducing heat buildup and surface wear. The split point tip at 135 degrees allows the bit to start on contact without walking, eliminating the need for a center punch in most applications. At 2.75 inches overall length with a 1.625-inch flute, this bit fits standard drill chucks and is sized for everyday production and maintenance drilling tasks performed by machinists, millwrights, and maintenance technicians.

This bit is suited for drilling steel workpieces in light manufacturing, HVAC fabrication, electrical panel work, and general mechanical maintenance. The 1/8-inch diameter and straight cylindrical shank make it compatible with standard keyed and keyless drill chucks on benchtop drill presses, hand drills, and magnetic base drills. The right-hand cutting direction and regular spiral flute geometry support efficient chip evacuation in through-hole and blind-hole drilling scenarios at moderate feed and speed rates.

Key Features

• TiN coating reduces friction and extends tool life compared to uncoated HSS
• 135-degree split point starts on contact and reduces thrust force required
• High speed steel construction handles steel and general ferrous workpieces
• Right-hand spiral flute promotes consistent chip evacuation
• Straight cylindrical shank fits standard drill chucks without adapters
• General-purpose grade suitable for maintenance, fabrication, and production drilling

Compatibility

Designed as a general-purpose jobber-length drill bit for use with standard drill chucks accepting a 1/8-inch straight shank, compatible with hand drills, drill presses, and magnetic base drills across trade and light manufacturing applications.

Installation Notes

This bit is installed and operated by machinists, maintenance technicians, and trade professionals using standard drill equipment. Secure the shank fully in the chuck and verify the chuck key is removed before powering the drill. Match spindle speed to the workpiece material and bit diameter per standard machining reference charts. Do not exceed the maximum drilling depth of 1.625 inches in a single pass without retracting to clear chips.
