Note:
Cobalt drill bits require slow RPM when drilling metals. The suested RPM is only for your reference. It may vary from different materials. You can start from a lower RPM and adjust it higher slowly. Once the bit can get into the workpiece. the adjustment should be stopped.
Features:
● M35 cobalt. 5% cobalt added for higher hardne and heat-resitance. The Rockwell hardne is up to 67. It can cut faster and has a long life, up to 12 times compared with the average HSS bit.
● Self centering. The guiding separation point of 135° rapid cutting is self centering, which can penetrate quickly with le preure. The straight handle can be firmly fixed and accurately centered, which is suitable for standard bit chuck and conventional round chuck.
● Efficient drilling without walking. Remove s and particleseasier and faster.
● The lowest cost per hole drilled. Solid cobalt steel drill bit body can be resharpened.
● Split point. Drill directly to the size needed without pre-drilling
● Fully ground. Heavy-duty fully ground body construction for minimal burr and accurate diameter.
● Bits for metal. Suitable for drilling non-heat treated metals, of which the hardne is le than HRC38, such as stainle steel, copper cast , galvanized , , and aluminum alloy. Not suitable for hardened steel / high carbon steel. If penetration is not poible, try adjusting the speed.
Notes: 1. The drill can drill stainle steel, but proceing stainle steel and other high hardne of the workpiece, it is recommended to be fixed on the drilling machine or platform type machine, the use of electric hand drill is prohibited, because the artificial use of electric hand drill is easy to shake, resulting in insufficient proceing accuracy Or the bit gets dull or even breaks. 2. The bit and the workpiece to be proceed must be fixed or clamped. Generally, the rotational speed is le than 2000RPM. The larger the diameter of the drilling hole, the lower the rotational speed. The harder the material is, the slower the speed is required, and the more durable the cutting fluid is recommended. 3. Can dry cut stainle steel and other high hardne metal, but continuous uninterrupted work is best to add water or coolant cooling, prolong the life of the product.
