Osg 1751605 Spiral Point Tap M10x1.50 Metric Coarse Tin Hss

Product Description

The OSG 1751605 is a spiral point tap designed for cutting M10x1.50 metric coarse internal threads in through-hole applications. Built from vanadium high-speed steel (HSS-E) and finished with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction in production tapping operations. The plug chamfer lead makes it well suited for through-hole work where chip evacuation ahead of the cutting edge is required. With a 6H class of fit and D6 thread limit, it produces threads within standard metric tolerance for general mechanical assembly. Licensed machinists, toolroom techs, and CNC setup operators are the primary users of this tap.

The OSG 1751605 is used in ferrous machining environments where metric coarse threads are required. Stated material applications include hardened steel, low-carbon steel, medium-carbon steel, and stainless steel. It is suited for production runs on machining centers, CNC lathes, and drill presses equipped with a tapping attachment. The right-hand thread direction and spiral point geometry make it compatible with standard CNC rigid tapping cycles. It carries OSG Series 342 designation, which covers general-purpose metric spiral point taps in this size range.

Key Features

• Spiral point geometry pushes chips forward and out of the hole, reducing clogging in through-hole tapping
• Vanadium HSS-E construction provides increased wear resistance over standard M2 high-speed steel
• TiN coating reduces friction, extends tool life, and improves chip flow in steel applications
• Plug chamfer (approximately 3-5 thread lead) allows easy starting in through-hole setups
• 6H class of fit and D6 thread limit meet standard metric tolerance requirements for general assembly
• Right-hand cut, no coolant-through, non-oversize, non-interrupted thread design for straightforward setup

Compatibility

Designed to cut M10x1.50 metric coarse threads in hardened steel, low-carbon steel, medium-carbon steel, and stainless steel workpieces. Intended for through-hole applications; not designed for blind-hole use where chip packing is a concern.

Installation Notes

This tap should be installed in a tap holder, collet chuck, or rigid tapping chuck rated for the spindle speed appropriate to the workpiece material. Secure the workpiece fully before threading operations and verify spindle alignment to avoid tap breakage. Apply cutting fluid or tapping compound appropriate for the workpiece material, particularly when tapping stainless steel. Always follow shop safety protocols and machine manufacturer guidelines when setting up tapping cycles.
