Value Collection JY9036757 M17x1.5 Straight Flute Tap Hss 6H

Product Description

The VALUE COLLECTION JY9036757 is a straight flute tap designed for cutting M17x1.5 metric fine internal threads in a variety of materials. Built from high-speed steel with a bright uncoated finish, it delivers consistent thread form in through-hole and blind-hole applications. The bottoming chamfer style allows threading close to the bottom of a blind hole, making it suitable for tight-clearance work. With four flutes and a 6H class of fit, this tap produces accurate, tolerance-controlled threads suited for precision fastener engagement. Overall length is 4.03 inches with a thread length of 1.81 inches. Machinists, toolroom technicians, and maintenance professionals are the primary users.

This tap is used in metalworking and machining operations where M17x1.5 metric fine threads are required. It is well suited for repair, production, and maintenance tapping in materials where straight flute geometry performs reliably, such as cast iron and brittle materials. The bottoming chamfer makes it a common choice for blind holes where a taper or plug tap has already been used to start the thread and final full-thread depth is needed near the bottom of the bore.

Key Features

• M17x1.5 metric fine thread form for precision fastener applications
• Bottoming chamfer allows threading to near full depth in blind holes
• High-speed steel construction provides durability across a range of workpiece materials
• 4-flute straight flute design suited for cast iron and other brittle materials
• 6H class of fit with D6 thread limit for controlled tolerance threads
• Bright uncoated finish — no coating to affect dimensional tolerance or chip flow

Compatibility

Designed as a standard M17x1.5 metric fine bottoming tap compatible with conventional and CNC tapping operations requiring a 6H thread tolerance class.

Installation Notes

This tap is installed and operated by machinists or maintenance technicians using a tap wrench, tapping fixture, or machine spindle. Ensure the workpiece is securely fixtured and the tap is properly aligned to the bore axis before applying cutting pressure. Use appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. When tapping blind holes with a bottoming chamfer tap, pre-thread with a taper or plug tap first to avoid tap breakage.
