TITANIUM | HIGH SPEED STEEL: classic high speed steel with titanium coating for proven capability and durability in drilling holes in plastic, aluminum, copper, stainless steel and many other types of sheet metal
135° SPLIT POINT TIP: increases cutting speed with self-centering and prevents walking
TWO-FLUTE DESIGN: clears chips faster and allows particles to escape easily
TRI-FLATTED SHANK: fits into power tools chuck securely and eliminates slip
HSS WITH 5% COBALT: Durable, Higher Heat & Abrasion Resistance.
PRECISE 135°SPLIT POINT & TWIST DESIGN: Prevent walking, clear chips and particles faster.
PROFESSIONAL & WIDELY USE: M35 Cobalt HSS is more suitable for hardened material. Particularly successful in 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.
ORGANIZED HOLDER: Set includes the drill bit holder with size index for easy storage and organizing.
【Combo Set of 13 Sizes】13 most commonly-used sizes (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") to satisfy all your needs. This drill bits set fits the majority of power drill currently on the market and come with a portable plastic bag for easy storage and organization.
【M35 Cobalt High Speed Steel】Industry grade 6542 high speed steel drill bit set, harder than 4241 HSS used in other similar drill bits set. These drill bits also contain 5% Cobalt, which increases wear-resistance and durability.
【Fully Ground Process & 135° Split Point】Fully ground spiral groove design clears particles quickly, decreases friction and heat for a faster and cooler drilling performance. 135° split point with straight shank prevents walking and makes drilling precise and faster. No center punch is needed.
【Multiple Application】Perfectly suitable for cutting Hard Metal such as Stainless Steel, Steel and Cast Iron as well as Wood, Aluminum Alloy and Other Softer Metals. × NOT for Glass or Ceramic Materials. ×NOT for High Carbon Steel and Heat-Treated Steel. √ Pay attention to speed, pressure and heat control during drilling.
【90 Days Warranty】If you are not fully satisfied for any reason, please contact us for 100% refund or replacement.
JOBBER LENGTH: jobber length cobalt drill bit, 135 degree split point reduces drill walking, 3-flat shank provides a secrue grip in chucks
MADE FROM HIGH-SPEED STEEL AND 5% COBALT: improve much higher heat resistance because of cobalt steel's high red hardness, provide strong durable performance compared to typical hss drill bits
CAN BE REPEATEDLY SHARPENED AS NEEDED: cobalt drill bit's hardness is uniform throughout the entire material, so that can be repeatedly sharpened without damaging the cutting edge allowing it to drill more than hss drill bits
APPLICATION: best used for drilling in hard metal, including stainless steel
INCLUDE: 13 pieces cobalt drill bits in inch sizes 1/16" to 1/4" (1/64" increments) with plastic case
