Accupro 18349-01C M6x1.00 Thread Forming Tap Bottoming Ticn

Product Description

The ACCUPRO 18349-01C is a bottoming thread forming tap designed for M6x1.00 metric coarse threading in blind hole applications. Unlike cutting taps, this forming tap displaces material rather than cutting it, producing stronger threads with no chips to manage. It is manufactured from powdered metal high-speed steel and finished with a TiCN coating for extended tool life in ferrous and non-ferrous materials. With a 6H class of fit and D9 thread limit, it meets standard metric tolerance requirements. Machinists and tool and die professionals install this tap in CNC machining centers, manual mills, and drill presses where blind hole threading is required.

This tap is suited for production and job shop environments handling metric threaded fastener applications in steel, aluminum, and similar workpiece materials. The bottoming chamfer with 2.5 chamfered threads allows threading close to the bottom of a blind hole, maximizing usable thread depth. A single oil groove supports lubrication during the forming operation. The overall length of 2.5 inches and shank diameter of 0.255 inches make it compatible with standard tap holders and floating tap chucks used in metric tooling setups.

Key Features

• Bottoming chamfer with 2.5 chamfered threads for maximum thread depth in blind holes
• TiCN coating increases surface hardness and reduces friction for longer tool life
• Powdered metal high-speed steel construction provides uniform grain structure and wear resistance
• Thread forming design eliminates chips, reducing the risk of chip packing in blind holes
• 6H class of fit with D9 thread limit meets standard metric tolerance specifications
• Single oil groove supports consistent lubrication through the forming cycle

Compatibility

Designed for use in standard tap holders and floating tap chucks configured for metric tooling with a shank diameter of 0.255 inches, suitable for blind hole threading operations in M6x1.00 metric coarse thread applications.

Installation Notes

Thread forming taps should be installed by qualified machinists or tooling technicians following standard machine tool lockout procedures before changing or setting tooling. Use the appropriate tapping fluid or cutting oil for the workpiece material to ensure proper lubrication through the oil groove. Verify tap holder runout and alignment before operation to prevent tap breakage. Do not exceed the recommended tapping depth of 1.0 inch for this tap in blind hole applications.
