Import BDNA--20751-1 Straight Flute Tap 5-44 Unf

Product Description

The IMPORT BDNA--20751-1 is a straight flute tap designed for cutting 5-44 UNF internal threads in metal workpieces. It features 2 straight flutes and a plug chamfer, making it suited for threading through-holes where chips can evacuate freely. Manufactured from high-speed steel (HSS) with a gold oxide coating, this tap resists wear and offers improved lubrication during the cutting process. The right-hand thread direction and H2 thread limit provide controlled tolerance for standard UNF fastener fitment. It is a compact, single-piece tap used in precision threading applications across machining, maintenance, and repair work.

This tap is appropriate for threading small-diameter holes in materials such as steel, aluminum, and other metals where a 5-44 UNF thread form is required. The plug chamfer style allows for gradual thread engagement over several leading threads, making it a practical choice for general-purpose tapping in both production and repair scenarios. It is typically used by machinists, maintenance technicians, and tradespeople performing precision fastener work on equipment assemblies.

Key Features

• 5-44 UNF thread size with 44 threads per inch for fine-pitch threading
• 2 straight flutes for chip clearance in through-hole applications
• Plug chamfer for gradual thread engagement and reduced entry force
• High-speed steel construction for durability across common metals
• Gold oxide coating improves wear resistance and reduces friction during cutting
• H2 thread limit ensures consistent tolerance control for standard UNF fasteners

Compatibility

Designed for cutting 5-44 UNF right-hand internal threads in standard through-hole tapping applications across metalworking and maintenance repair operations.

Installation Notes

This tap is installed using a standard tap wrench or machine tap holder. Always use appropriate cutting fluid to reduce heat and extend tool life. Ensure the workpiece is securely fixtured before tapping. Apply steady, even pressure and back off periodically to break chips and prevent tap breakage.
