Short DescriptionHEAVY DUTY COBALT+ TIN DRILL 4.50MMSP/PT DIN371 HSS-COBALT TAP M8X1.25 BLACK RINGHSS-G METAL DRILL BIT 2.2MM
Long DescriptionHeavy-duty drill used to drill steels with a tensile strength up to 1,400 N/mm2. Stainless steels, heat and acid resistant steels and phosphor bronze. TiN coating provides longer tool life. Point angle: 135°. Helix angle: normal. Web thickness: strengthened. Relief angle: normal. Tolerance of diameter: h8, Supply unit. All diameters - 1 pce. Manufactured to DIN 338 RN.ISO Metric - Spiral Point/Gun Nose - HSS-E Bright Finish For through holes. Taper lead to DIN form B. Tapping tolerance to 6H. The unique general purpose properties of these taps guarantee high productivity by reducing the amount of time spent changing taps for different materials and at the same time reduces the number of taps required by the machine shop. Swiss+Tech ‘Black Ring’ machine taps with their wide range of applications are the result of years of experience in metal cutting. Responsible for our developments were the following demands from our main customers: - Increase of a tap’s versatility. - Reducing the confusing type variety. - Reducing the storage costs for the tools. - Reducing the tool changing times. For general tapping applications. For production tapping of specific materials a specialist tap may be more suitable. Manufactured to DIN 371/376. The tool geometry (with up to 138 parameters) has been developed and optimised during long-term tests in co-operation with users for the different sections of structural steel, aluminum casting, machining steel, VA-steels, heat-resistant steels and tool steels. Selected hard coatings increase the range of applications. The objective of developing Swiss+Tech's ‘Black Ring’ Taps was the realisation of narrower tolerances and more efficient cutting times for the thread production.Bosch Twist Drill allows around 40% faster drilling and around 50% reduced pressure when drilling compared to standard HSS Drill Bits making them suitable for drilling through non-alloyed and alloyed high tensile steel, malleable and cast iron, hard plastics, non-ferrous metals plus sintered iron.
