Three-Edged High Speed Steel Drill Maintains Tool Life
IMTS 2018: Mapal’s Tritan-Drill series of three-edged drills now includes an HSS model for small-series production.
Mapal’s Tritan-Drill series of three-edged drills now includes an HSS version for small-series production.
According to the company, the shape of the main cutting edge makes the HSS drill robust even in difficult conditions.Stable cutting edge corners reduce damage to the cutting edge for smooth machining. The coating of the drill suits a range of different materials and increases tool life.
The drill features point geometry designed to eliminate piloting and center-punching. According to the company, it achieves higher feed rates than twin-edged HSS drills. With a pronounced tip reducing the chance of slipping over the chisel edge, it can also be used with hand drilling units. Diameters range from 8 to 40 mm.
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.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.
