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.
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.
【Industrial Grade M35】: High-speed steel drill bit set, these drill bits contain 5% cobalt, which is much harder than the high-speed steel used in similar drill bit sets. Fully ground drill bits with smooth surface, high grinding precision, and sharp edges can reduce friction between the drill bit and the material and reduce the temperature of the drill bit during operation.
【Enhanced Precision Design】: Adopts 135° split point tip for faster penetration and less walking. Deep groove twist drill bit design ensures smooth chip evacuation and stable operation, providing accurate results for demanding work.
【Convenient Size Selection】: This 19 pcs M35 drill bit set includes everything you need to meet all your needs, bringing a user-friendly experience. Set includes: 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm [1-10mm, in 0.5mm increments].
TOUGH: The Bosch CO14 Drill Bit Set is manufactured from cobalt for drilling in hard and abrasive materials such as stainless, cast iron, and high-density metal. Also useful for general drilling in light-gauge metal, wood, and plastic.
RELIABLE: The three-flat shank design promotes better grip and guards against slipping on bits 3/16 in. and larger
ACCURACY: Featuring a no-skate split-point tip for clean, precise holes and accurate starts.
Various Sizes 13 sets of drill bits include 1/16", 5/64", 3/32", 7/64", 1/8", 9/64", 5/32", 11/64", 3/16", 13/64", 7/32", 15/64", 1/4", can meet more needs.
Quick and Efficient The cobalt drill bit set can be used effectively on most soft and hard objects, with a 135 degree point tip and twist design for faster cutting, self-centering to prevent walk-off and faster chip and particle removal.
M35 Cobalt Drill Bit The M35 cobalt drill bit is a durable, sharp and robust drill bit suitable for cutting stainless steel, iron castings, copper, aluminum and other soft metals as well as plastics, wood etc.
Quality material: Manufactured from M35 cobalt steel, with molybdenum and cobalt added to creates a hardened alloy, measuring Rockwell hardness up to 67, for much faster cutting and extra longer life span, with up to twelve times when compared with an average HSS drill bit. Precision treatment makes drills durable toughness, withstands heavy duty operation, resists corrosion and lubricates the drill bits better for cutting smoothly.
Precise & Efficient Drilling Performance: Fully Ground spiral groove design clears particles quickly,decreases friction and heat for a faster and cooler drilling performance. twist drill bits have precise diameter; M35 cobalt drill bits for hardened metal are not easy to break or wear out, ideal for heavy duty hole drilling.
Great working performance: This cobalt drill bit set is stable and not easy to break, resistant to higher heat and abrasion, and convenient as working tool. 135ｰSPLIT POINT - the 135ｰquick-cut split point are self-centering and able to penetrate metals quickly with less pressure, prevent bits from "walking and wanding". Easy cutting without need of center punch.
