Scientific Cutting Tools TM295-14N Thread Mill 7/16-14

Product Description

The SCIENTIFIC CUTTING TOOLS TM295-14N is a straight flute thread mill designed for cutting 7/16-14 UNC threads in both external and internal applications. Built from powdered metal and finished with a TiCN coating, this tool delivers reliable wear resistance and thermal stability in production machining environments. It runs 4 flutes with a 0.295-inch cutting diameter and a 0.814-inch length of cut, making it well suited for threading operations where a single tool must handle both thread directions. Machinists and CNC programmers in job shops and production facilities are the primary users of this tool.

This thread mill is intended for use on CNC machining centers capable of helical interpolation. It handles 7/16-14 UNC external and internal threading in a single tool, reducing the need for tapping and the associated tap breakage risk. It is appropriate for use in ferrous and non-ferrous metals where TiCN coating provides adequate lubricity and hardness. The 3/8-inch shank diameter fits standard ER and end mill collet systems common across most machining center spindles.

Key Features

• Straight flute geometry for stable, low-vibration thread milling in both external and internal configurations
• TiCN coating improves surface hardness and reduces friction for longer tool life in steel and cast iron
• Powdered metal substrate provides consistent grain structure and edge integrity throughout the cutting length
• 4-flute design balances chip evacuation with cutting stability at typical thread milling feed rates
• 3/8-inch shank diameter fits standard collet toolholders without adapters
• 14 teeth per inch matches 7/16-14 UNC thread form for single-pass helical interpolation

Compatibility

Designed for machining centers capable of helical interpolation and programmed for 7/16-14 UNC thread milling in external and internal applications. No specific machine model compatibility is stated by the manufacturer for this tool.

Installation Notes

Install the tool in a clean, properly sized collet or end mill holder and verify runout before cutting. Program the CNC control for helical interpolation at the correct thread pitch and cutting diameter offset. Power down the spindle and secure the tool fully before making any toolholder adjustments. Follow shop-specific speeds and feeds for the workpiece material and consult the tool manufacturer's application data for starting parameters.
