Features&B e n e fit s of M35 Cobalt Twist Drill Bits
Features&Benefits of 37PCS Screwdriver Set
✔️ HSS M35 Material : The HSS M35 drill bit is a cobalt alloyed high performance drill bit. Even with insufficient cooling it has reserve in heat resistance. Due to the alloying addition of 5 % Co in the cutting material these drill bits can be used for working with work pieces with a tensile strength of over 800N/m².
✔️ Lowest Cost Per Hole Drilled : Cobalt bits are more expensive than ordinary HSS drill bits. But if you regularly drill metals, they are a good investment since they tend to last longer. With an extended life, you can lower cost per hole drilled.
✔️ Fully Ground Technic : HSS-G (ground) is cut in their shape with the help of diamond tools and cooled during the process. Use HSS-G for more precise work because they are better centered generally and perfectly symmetrical.
✔️Split Point : For drills with very strong cores, for particularly tough, hard materials and for deep-hole drills. Split Point features good centring, little pressure required. Chip spreading improves chip removal.
✔️135° Point Angle : The 135º high performance cutting edge ensures a very high aligned preciseness. The point angle is located on the head of the twist drill. The angle is measured between the two main cutting edges at the top. A point angle is necessary to center the twist drill in the material.The larger the point angle, the shorter the tapping time.
✔️40° Helix Angle : The 40º helix angle enables a perfect and fast chip removal and provides a high cutting speed along with increased stability and accuracy.
✔️Wide Groove Profile : Wider groove profile takes a better chip absorption and removal. Poor chip removal means a higher heat development, which in return can lead to annealing and ultimately to breakage of the twist drill.
✔️Titanium Coating : The titanium coating on the drill bit helps to reduce overheating. It’s the reason that this bit has a lifespan up to six times longer than other comparable drills.
✔️Straight Shank : Straight shank for standard drill chuck, less "walk" or "wander". The end of shank is chamfered to allow easy and firm holding.
✔️Applications : Best for < 900 N/mm2 and < 11 00 N/mm2 Steel. For cutting through hard metals such as stainless steel, cast iron, high temperature alloy, titanium alloy, hard plastics and woods, and also can be used for softer materials.
✔️37PCS Screwdriver Set - A Free Gift : Made of sand-blasted high grade carbon steel, these bits are built to stand up to any project. Quick change adapter is included for fast switching between sizes. For your most frequent projects. Easily hang pictures, kitchen fixtures, curtains, shelving, towel racks and more
