Osg 1755801 Spiral Flute Tap M14x2.00 Bottoming 6H

Product Description

The OSG 1755801 is a spiral flute bottoming tap designed for cutting internal metric threads in a range of ferrous materials. Built from vanadium high-speed steel with a steam oxide coating, this tap delivers the hardness and lubricity needed for demanding threading applications. It cuts an M14x2.00 metric coarse thread to a 6H class of fit with a D7 thread limit. The 45-degree helix angle drives chips up and out of the flute, making it well-suited for blind-hole applications where chip evacuation is critical. Overall length is 3-19/32 inches with a thread length of 1.6563 inches. Machinists and tool-and-die professionals are the primary users.

This tap is intended for threading blind holes in stainless steel, high-carbon steel, low-carbon steel, and medium-carbon steel. The bottoming chamfer allows threading close to the bottom of a hole, making it the correct choice when full thread depth near the hole base is required. It belongs to OSG Series 343 and is suited for both CNC machining centers and manual tapping operations where a rigid setup and appropriate tapping fluid are used. Coolant-through is not supported on this tap.

Key Features

• M14x2.00 metric coarse thread profile to 6H class of fit with D7 thread limit
• Bottoming chamfer for maximum thread engagement in blind holes
• 45-degree right-hand spiral flute geometry for upward chip evacuation
• Vanadium high-speed steel construction for elevated wear resistance and toughness
• Steam oxide coating reduces friction and improves chip flow
• Compatible with stainless steel, high-carbon, low-carbon, and medium-carbon steel workpieces

Compatibility

Designed for threading M14x2.00 metric coarse blind holes in stainless steel, high-carbon steel, low-carbon steel, and medium-carbon steel. Part of OSG Series 343.

Installation Notes

Tapping operations should be performed by a qualified machinist following standard shop safety practices. Always secure the workpiece and ensure the tap is properly aligned with the pre-drilled pilot hole before engaging. Apply an appropriate tapping fluid or cutting oil for the workpiece material to extend tool life and improve thread finish. Inspect the tap for wear or chipping before each use and replace if damaged to avoid thread damage or tap breakage in the hole.
