Description: Metric M42 8% Cobalt Twist Drill Bits Set for Stainless Steel and Hard Metal (1Mm-10Mm/19Pcs) Premium M42 8% Cobalt Steel ,68-70 HRC (Rockwell Hardness Scale) ,Usually Give the Best Heat,Wear and Chip Resistance and Long Tool Life.3 Steps Design for Cutting through Stainless Steel,Hard Metals,Aluminum,Plastic.This Cobalt Drill Bit is Typically Capable of Running Three to Five Times Faster.Despite the Higher Price,the Cost Per Hole When Using Cobalt Drill Bit Will be the Lowest,Since It Can Produce So Many More Holes.The Sufficiently Sharp Bit Edge Can Cut the Metal Material into Long Strips of Iron Chips rather than Slowly Grinding Throng the Material with a Blunt Drill Bit.19Pcs 135 Degree Split Point Drill Bits Includes :1mm(length:3.4cm) 1.5mm 2mm 2.5mm 3mm 3.5mm 4mm 4.5mm 5mm(length:8.5cm) 5.5mm 6mm(length:9cm) 6.5mm 7mm 7.5mm 8mm(length:11.5cm) 8.5mm 9mm 9.5mm 10mm(length:13cm) [DIA 0.5mm Increments] . Product Description STROTON Metric M42 8% Cobalt Twist Drill Bits Set for Stainless Steel and Hard Metal (1mm-10mm/19pcs) Why choose STROTON cobalt drill bits? The research shows that HSS with cobalt has a higher temperature resistance and Red hardness, a greater wear resistance(Hardness) and a higher heat treat response than HSS without cobalt . Red hardness, it causes the hardened steel to have an ability to maintain hardness at approximately 860-880 ℃.Higher Tempering resistance,it means to maintain a high hardness at high temperatures for an extended period of time.68-70 HRC,it means that the drill bits has 3X cutting ability and 2X durability.This drill bits set is made of Premium Cobalt (80,000 dollars per ton). M42 Cobalt 8% Alloy This drill bits set is made of Premium Cobalt (80,000 dollars per ton).Holds up better than generic high-speed steel,8% Cobalt gives high-speed steel more heat and wear resistance. 3 Steps . Design (3X-5X Drilling Efficiency) 3 Steps design tip starts drilling immediately with less force and eliminates "walking" across the work surface.Ideal for Stainless steel and Hardmetal,Hardwood,Aluminum,Copper,Plastic and Hardwood. Ideal for Metal and Hardwood Suitable for drilling Stainless Steel,Hard Metals,Aluminum,Copper,Plastic and Hardwood.The 3 steps design makes it accurately centered for woodworking jobs that require precision drilling.Also, the cobalt-containing design makes it perform even better in hardwood drilling. The drill bit should be perpendicular to the workpiece when used. Non-vertical use may cause the drill bit to break.Using a drill press with sufficient power will make drilling easier.Do not use the drill bit on a percussion drill.This Drill bit can not be used on glass, walls and concrete. Controling the drill speed from 200 to 1000 RPM would make it easier for you to drill holes on stainless steel. A high RPM does not improve drilling efficiency, but rather increases the heat between the bit and the workpiece, which may cause the bit to soften and the workpiece to harden.Drill diameter≤5mm,RPM(1000~700)5-10mm,RPM(700~350)10-15mm,RPM(350~200) Using cutting fluid will make the bit last longer. Add stainless steel tapping oil or engine oil to prevent the stainless steel from overheating and forming a very hard oxide layer.It also works adding some vinegar,soy sauce or water if you don't have engine oil.
