Description
- 【HSS Cobalt Cone Drill Bit】Cone step drill bit is made of HSS with cobalt (M35), the addition of cobalt makes the cone drill bits have excellent hardness and wear resistance, longer service life; it also increases the hot hardness of the cone drill bits, so that the Step Cone Drill Bit can maintain good cutting performance even at high temperatures.
- 【0-5 mm Application Range】HSS stepped drill bit is available for material thicknesses in the range of 0-5 mm, suitable for drilling, reaming and deburring work on thin materials such as stainless steel (<1mm), carbon steel, sheet iron, sheet aluminium, sheet copper, sheet plastic, etc. Note: Not suitable for tile walls.
- 【15 Steps Cone Cutting Drill】Grooved Cone Drill Bit offers a variety of cutting diameter options from 4mm to 32mm (4/6/8/10/12/14/16/18/20/22/24/26/28/30/32mm) with a total of 15 steps. Fulfils the requirements of different hole diameters without changing the drill bits.
- 【10 mm shank Cone Drill Bit】Unique groove design ensures good chip evacuation; 118°"X" opening for more stability when drilling. The triangular shank with a diameter of 10 mm is suitable for most standard electric drills, cordless drills, hand drills and bench drills.
- 【Note】When working with cone cutter drill bit, you need to add water to continuously cool down the temperature, which can effectively extend the service life of the step drill bit hss. The larger the drill diameter, the lower the speed should be to better protect the cutting edge.
