YG-1 D2GP185004 Jobber Drill 1/16 Inch Hss Tin

Product Description

The YG-1 D2GP185004 is a high speed steel jobber-length drill bit designed for general-purpose drilling in steel and similar workpiece materials. It measures 1/16 inch (0.0625 inch) in diameter with an overall length of 1-7/8 inches and a flute length of 7/8 inch. The 135-degree split point geometry reduces walking on entry and lowers the thrust force required to start a hole, making it well suited for production and maintenance drilling without a center punch. A titanium nitride (TiN) coating increases surface hardness and reduces friction to extend tool life in repetitive drilling applications.

This drill bit is intended for drilling steel and comparable ferrous materials in general shop, maintenance, and fabrication environments. The right-hand, regular spiral flute configuration provides efficient chip evacuation in standard through-hole and blind-hole applications. The straight cylindrical shank at 1/16 inch diameter accepts standard drill chucks found on benchtop drill presses, cordless drills, and hand drills. With a flute-by-diameter ratio of 14xD, this bit is suited for moderate-depth holes within the 7/8 inch maximum drilling depth.

Key Features

• 135-degree split point reduces bit walking and entry thrust without requiring center punching
• TiN coating improves surface hardness and reduces friction for extended tool life in steel drilling
• High speed steel construction provides toughness and heat resistance in general-purpose drilling
• Right-hand, regular spiral flute promotes efficient chip evacuation in ferrous materials
• Straight cylindrical shank fits standard drill chucks; no flats, no adapters required
• Two-flute design balances chip clearance with wall finish on small-diameter holes

Compatibility

Designed as a general-purpose jobber drill bit for use in steel and similar primary workpiece materials. Compatible with any standard drill chuck sized to accept a 1/16 inch straight shank.

Installation Notes

This bit is installed and removed by a licensed or qualified machinist, maintenance technician, or fabricator using a standard keyed or keyless drill chuck. Ensure the drill press or hand drill is powered off and unplugged before changing bits. Use appropriate cutting fluid or lubricant when drilling steel to manage heat buildup and extend bit life. Do not exceed the rated drilling depth of 7/8 inch without retracting to clear chips.
