Guhring 9055220016000 Jobber Drill Bit 1.6mm Tin Pm

Product Description

The GUHRING 9055220016000 is a jobber-length drill bit designed for precision drilling in cast iron and steel. Built from powdered metal (PM) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction in demanding production environments. The bit measures 1.6 mm in diameter with a 130-degree cone relief point, a parabolic flute design, and an overall length of 43 mm. The straight-cylindrical shank and web-thinned tip reduce entry force and improve chip evacuation. This is a high-performance tool intended for machinists and tool-room professionals working with ferrous materials.

This drill bit is suited for close-tolerance drilling operations in steel and cast iron workpieces, both in job shop and production settings. The parabolic flute geometry supports efficient chip removal at higher feed rates, making it appropriate for CNC machining centers, drill presses, and manual mills. The Series 5522 conforms to DIN 338 standards, placing it within a recognized international specification for jobber-length twist drills. Coolant-through capability is not supported on this bit, so flood or mist external coolant delivery is the appropriate method when cutting fluid is required.

Key Features

• Powdered metal construction with TiN coating for extended wear resistance in ferrous materials
• 130-degree cone relief point angle optimized for cast iron and steel entry
• Parabolic flute geometry promotes rapid chip evacuation and reduces heat buildup
• Web-thinned tip lowers thrust requirements and improves centering accuracy
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Conforms to DIN 338 specification for jobber-length twist drills

Compatibility

Designed as an OEM-specification replacement or production consumable for machining applications involving cast iron and steel workpieces, consistent with DIN 338 jobber-length drill bit standards.

Installation Notes

Installation is performed by licensed machinists or qualified toolroom personnel. Secure the straight-cylindrical shank firmly in a drill chuck or collet to the full recommended engagement depth before operation. Confirm spindle speed and feed rate are appropriate for a 1.6 mm diameter bit in the target material before starting the cut. Do not use this bit in impact drivers or hammer-drill mode.
