7 Differences between HSS and Cobalt Drill Bits

  • Drill Bits Classification Depending on The MaterialsWhat Are HSS Drill bits?What Are Cobalt Drill bits?Summary and General SuggestionSpeed and Feed Calculator - Whitney Tool Company35 rows · High Speed Steel Cobalt Tool Steel Uncoated Carbide . Coated Carbide. NON-FERROUS Drill Feeds and Speeds - America's Finest High-Speed Feed equals.001" per revolution for every 1/16" of drill diameter, plus or minus.001" on the total. Speed equals 80 surface feet per minute in 100 Brinell hardness material and the speed should be reduced 10 surface feet per minute for each additional 50 points Brinell hardness.

    Speed equals:80 surface feet per minute in 100 Brinell hardness material and the speed should be reduced 10 surface feet per minute for each additional 50 points Brinell hardness. Feed and speed rates:should be reduced up to 45-50 when drilling holes deeper than 4 drill diameters. Feeds and Speeds - Formulas Drilling 4140 Annealed. Feeds/speeds/drill selection Mar 23, 2012 · We decided to go for some carbide tipped drills and two toasted in 6 holes. Tips were chipped and one flute was cracked. Here are the previous parameters. S1300, F6, Flood coolant, peck .200. We decided to go get some cobalt screw lengths to get it done but seems the decision on feeds/speeds varies greatly from SUPER ass slow, to slow with high Drills:Twist Drill Extra Length HSS, Cobalt, Coolant Drills:Twist Drill Extra Length HSS, Cobalt, Coolant Through Series 905 Part Number:905- Twist Drill Extra Length High Speed Steel, Cobaltl, Solid Coolant Through Inch & Metric

    High-speed steel drill bit - All industrial manufacturers

    for non-ferrous metals high-speed steel step. insert drill bit. SSHS. Diameter :4 mm - 40 mm. Step drill It is made of super-hard high - speed steel with a diameter from 4 mm to 40 mm and a combination of steps from 4 steps to 13 steps, including spiral grooves Machining - HASTELLOY.COMCarbide tipped or high speed steel drills are recommended. Surface speed:30-35 surface ft./min (0.15-0.18 m/s) for carbide tipped drills; 8-10 surface ft/min (0.04-0.05 m/s) for high speed steel drills. Feed rate:0.004 in (0.1 mm) per revolution for 0.25 in (6.4 mm) diameter and greater. 135° included angle on point. Milling (ULTIMET® alloy) Parabolic HSS/HSCO/PM Drills - GUHRINGParabolic HSS/HSCO/PM Drills. A general purpose high speed steel (HSS) or cobalt (HSCO) drill with a standard flute design can be replaced with a Guhring GT (parabolic flute) drill, and production rates and part quality can both be significantly improved.The unique flute form of the parabolic drill contributes to increased chip flow which improves heat dissipation within the cut.

    Roughing End Mills Machine Tools Regal Cutting Tools

    Roughing End Mills - Cobalt and High Speed Steel. Regal Cutting Tools manufactures a variety of roughers for a wide range of materials and conditions. Heavy cuts can be achieved because our roughing end mills have a much higher effective feed per tooth than a conventional end mill. Normally a 20% reduction in effective horsepower is used.
