Value Collection JY9036922 Straight Flute Tap M27x1

Product Description

The VALUE COLLECTION JY9036922 is a straight flute tap designed for cutting M27x1 metric fine internal threads in a wide range of metalworking and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable thread-cutting performance in ferrous and non-ferrous materials. The bottoming chamfer style allows threading close to the bottom of blind holes, making it well-suited for precision work where full thread depth is required near the base of a bore. With 4 flutes and a 6H class of fit, this tap produces clean, accurate threads that meet standard metric fine tolerance requirements. Overall length is 5.125 inches with a thread length of 2.5 inches.

This tap is used in machine shops, tool-and-die operations, and maintenance environments where M27x1 metric fine threads are specified. The bottoming chamfer configuration is typically chosen when through-hole taps cannot reach the required thread depth, or when parts must mate with fine-pitch fasteners that engage near the bottom of a blind bore. Right-hand thread direction is standard. It is suited for use in manual tapping handles or machine tapping setups operating at appropriate speeds for HSS tooling in the target material.

Key Features

• M27x1 metric fine thread profile for precision-pitch applications
• Bottoming chamfer allows full threading depth in blind holes
• 4-flute design provides good chip control and thread finish
• 6H class of fit meets standard tolerance requirements for metric fine threads
• High-speed steel construction offers durability across a range of workpiece materials
• Bright, uncoated finish — no coating buildup to affect thread tolerance
• Right-hand thread direction, D5 thread limit

Compatibility

Designed for cutting M27x1 metric fine internal threads. Suitable for use with standard straight flute tap holders and machine tapping setups that accept the corresponding shank size for this tool class.

Installation Notes

Tapping should be performed by a machinist or qualified tool operator familiar with cutting speeds and feeds appropriate for HSS taps in the target material. Ensure the workpiece is securely fixtured and the tap is properly aligned with the pre-drilled hole before engaging. Use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. For bottoming taps, take care to advance in controlled increments when approaching the bottom of a blind hole to avoid tap breakage.
