Guhring 9010910080000 M8x1.25 Bottoming Hand Tap Ticn Hss

Product Description

The GUHRING 9010910080000 is a straight-flute hand tap designed for cutting internal M8x1.25 metric threads in blind holes. Manufactured from high-speed steel with a TiCN (titanium carbonitride) coating, it delivers improved wear resistance and reduced friction compared to uncoated HSS tooling. The bottoming chamfer style allows threading close to the bottom of a blind hole, making it well suited for applications where thread depth is critical. With a 3-flute design and a 90 mm overall length, this tap is built for controlled, hand-driven or machine-assisted tapping operations performed by machinists, toolroom technicians, and maintenance professionals.

This tap is rated for blind hole threading in a range of workpiece materials including aluminum, cast iron, steel, and hardened steel. The through-coolant feature supports use in CNC tapping operations where coolant delivery through the tool helps clear chips and manage heat. The 6HX class of fit with D5/D6 thread limits produces a standard tolerance metric thread suitable for general fastener applications. It is a Series 1091 tap conforming to metric thread standards.

Key Features

• Bottoming chamfer for threading to near the bottom of blind holes
• TiCN coating for increased surface hardness and reduced tool wear
• Through-coolant capability for chip evacuation in CNC tapping setups
• 3-flute straight-flute geometry suited to a wide range of machinable materials
• 6HX class of fit with D5/D6 thread limits for standard metric thread tolerance
• High-speed steel construction provides toughness across varied material applications

Compatibility

Designed for M8x1.25 right-hand metric blind hole threading applications in aluminum, cast iron, steel, and hardened steel workpieces. Suitable for hand tapping and CNC machine tapping operations that support through-coolant tooling.

Installation Notes

This tap should be installed by a qualified machinist or toolroom technician familiar with thread-cutting operations. Ensure the workpiece and machine spindle are properly secured and aligned before tapping to avoid tap breakage. When used in a CNC setup, confirm that the machine tapping cycle and coolant pressure are compatible with through-coolant tooling. For hand tapping, use a properly sized tap wrench and apply consistent, controlled torque with periodic reversal to break chips.
