Guhring 9006520043700 Jobber Drill 11/64 in Hss Tin

Product Description

The GUHRING 9006520043700 is an 11/64 inch (0.1719 inch) diameter jobber-length drill bit designed for high-productivity metal drilling in industrial and trade applications. Built from heavy-duty high speed steel (HSS) and finished with a titanium nitride (TiN) coating, the bit runs cooler and resists wear significantly longer than uncoated HSS tooling. The 130-degree split point geometry — combined with a web-thinned, tapered web — reduces thrust force at entry and improves chip evacuation. The parabolic flute profile is optimized for fast chip removal, making this bit well-suited to deeper holes and tougher materials. Overall length is 3-5/32 inches (3.1563 inches), and maximum drilling depth reaches 1.5930 inches.

This bit is rated for primary workpiece materials including steel, cast iron, aluminum, and other non-ferrous metals. It conforms to DIN 338 standards, which define jobber-length geometry and tolerances widely used in European and North American CNC and manual drilling operations. The straight cylindrical shank (11/64 inch diameter) seats directly in standard drill chucks and is compatible with benchtop drill presses, hand drills, and CNC machining centers. The Series 652 designation places this bit within GUHRING's heavy-duty jobber line, intended for shops and field technicians who require consistent performance across high-volume drilling cycles. Flute-to-diameter ratio is 5xD.

Key Features

• 11/64 inch (0.1719 inch) diameter with DIN 338 jobber-length geometry
• TiN coating extends tool life and reduces friction on steel, cast iron, and non-ferrous workpieces
• 130-degree point angle with web thinning lowers entry thrust and improves centering
• Parabolic flute design promotes rapid chip evacuation in deeper holes (max depth 1.5930 inches)
• Right-hand cutting direction; straight cylindrical shank fits standard drill chucks without adapters
• Heavy-duty grade HSS construction built to DIN 338 specification

Compatibility

Designed as an OEM-specification replacement or direct-use jobber drill for standard drill chucks accepting an 11/64 inch straight shank; compatible with hand drills, drill presses, and CNC spindles rated for the 5xD flute-by-diameter ratio per DIN 338.

Installation Notes

Machinists and industrial maintenance technicians should secure the straight shank fully within the chuck jaws before tightening to prevent runout. Power down and lock out any machine before changing bits. Confirm chuck capacity accepts the 11/64 inch shank diameter prior to installation. Cutting fluid or mist coolant is recommended for extended runs in ferrous materials, even though this bit does not feature through-coolant capability.
