Guhring 9044095048260 Spiral Flute Tap 10-32 Unf

Product Description

The GUHRING 9044095048260 is a spiral flute tap designed for blind hole threading in a wide range of ferrous and non-ferrous materials. Built from cobalt high-speed steel with an oxide finish, this 10-32 UNF tap runs a 40-degree helix angle that efficiently evacuates chips upward out of the hole during the tapping cycle. The modified bottoming chamfer allows threading closer to the bottom of blind holes than a standard plug tap. It is suited for production environments and job shop use where consistent thread quality in 2B/3B class-of-fit applications is required.

This tap is intended for blind hole threading operations in materials including alloy steel, alloy tool steel, aluminum alloy, case-hardened steel, cast iron, ductile iron, free-cutting steel, heat-treated steel, malleable cast iron, stainless steel, structural steel, and tool steel. The 3-flute, right-hand spiral flute geometry with a fast flute style makes it effective in CNC machining centers and manual drill press setups where chip control in interrupted or deep blind holes is a concern. Series 4409 identifies the GUHRING product family for this configuration.

Key Features

• Cobalt HSS construction provides heat and wear resistance in hard and abrasive materials
• 40-degree right-hand helix angle pulls chips up and out of blind holes during threading
• Modified bottoming chamfer for threading close to the bottom of blind bores
• Oxide finish reduces friction and provides light corrosion resistance during storage and use
• H5 thread limit for controlled oversize suitable for 2B/3B class-of-fit tolerance
• 3 right-hand spiral flutes with fast flute style for efficient chip evacuation

Compatibility

Designed for 10-32 UNF blind hole threading applications across a broad range of workpiece materials including alloy steel, stainless steel, aluminum alloy, cast iron, and tool steel. Compatible with standard 0.194-inch shank tool holders and machine tap chucks accepting this shank diameter.

Installation Notes

This tap is installed and operated by machinists and tool-and-die professionals in CNC or manual tapping applications. Ensure the spindle and workpiece are fully secured before beginning the tapping cycle, and use appropriate cutting fluid for the workpiece material to extend tool life. Verify the tap holder provides adequate float to avoid thread distortion or tap breakage. Always confirm the correct pre-drill diameter for a 10-32 UNF thread before tapping.
