Carmex's Mini Spiral Mill-Thread Tool Reduces Chatter
The Mini Spiral Mill-Thread series from Carmex Precision Tools is now available in inch sizes as well as metric.
Designed for smooth cutting operations at high feed rates, the Mini Spiral Mill-Thread series from Carmex Precision Tools is now available in inch sizes as well as metric. Featuring an internal coolant bore, the spiral-fluted toolholders hold one to three inserts. The spiral design is said to reduce vibrations and chatter, resulting in a high-quality surface finish. They are available in small cutting diameters.
“The popularity of the Mini Spiral Mill-Thread line in metric dimensions has created a demand for offering the line in inch sizes,” says Jim White, national sales manager. “The variety of sizes and the availability of the MT7 sub-micron grade with multi-layer TiAIN coating offer customers a range of choices and the assurance of longer tool life.”
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
Consider these alternatives when conventional drilling can't do the job.
