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.
Thread milling and tapping are two methods for machining threads in a hole. Tapping is more popular, but thread milling has several advantages that might be important in your application.
Recent tap geometry refinement and advances in coating technologies have made the chip-less, cold-forming operation suitable for a wider range of workpiece materials.
The recipe for best results is simple: Start with a rigid machine, add a high pressure through-the-spindle coolant system, then combine these with the right drill geometry plus the right speeds and feeds.
