Faithfull Long Series 8.5mm Pre-Pack HSS Jobber Drill

Manufactured To DIN338 Standard From M2 Grade HSS Material

Worked on Most Material - M35 HSS twist drill bit for the professional machining of metals, stainless steel, cast iron, alloy steel, hard plastics, wood.

Manufactured to DIN 338 and ISO 235 1 Specifications

High heat and wear resistance

For drilling in metal, eg when pre-drilling for anchors, rivets, and threads or drilling in steel beams for installations, and fixtures

Professional Drill Bit Precise 135 self-centring tips, twist drill bit kit will not "walk" or "wander", clear chips and particles faster. Produced by precision fully ground which ensures chips move smoothly. Conforms to DIN 338.

Professional Drill Bits - Made of M35 high speed steel with titanium nitride coated, 135 self-centring tips, according to DIN 338 & BS328 Standard.

Strength and Hardness - Made of high-speed steel. HSS(High Speed Steel) enables the drill body harder and can keep a longer drilling life.

Wide Applications The drill bits can drill clean and accurate holes in stainless steel, cast iron, A3 steel, carbon steel, aluminum alloy, copper, wood and plastic. Sharp cutting edges provide neat and smooth cuts. Large spiral grooves facilitate the export of metal chips.

WIDE APPLICATION M35 Cobalt HSS drill bits are purposely forged to work on hardened materials. Mainly used in cutting through hard metals such as steel, stainless steel, cast iron, high temperature alloy, titanium alloy, hard plastics and woods, and also can be used for softer materials

Easy to Use

Twist Drill Bits Cutting edge diameter 8.5mm 0.335"; round shank diameter 8.5mm 0.335"; cutting edge length 79mm 3.11"; overall length 116mm 4.57"; split point 135 degree. Used with hand drills, drill presses, bench drills, machining centers, CNC lathes, etc.

MATERIAL HSS - 4341 8.5mm jobber drill bits made from high-speed steel (HSS) 4341, known for its durability and toughness. The drill bits feature a black oxide finish, providing a dry rust-resistant coating that ensures faster cutting speeds and a longer lifespan.

Strength and Hardness - Made of high-speed steel. HSS(High Speed Steel) enables the drill body harder and can keep a longer drilling life.

For Drilling Carbon And Alloy Steel, Non-Ferrous Metal, Plastics & Wood - Use A Cooling Agent And Drill At Slow Speeds When Drilling Metals

HSS Cobalt Long Series Drill Bits - For drilling particularly tough or hard metal drilling applications such as stainless steel, hardened metal, cast iron, Cr-Ni and special acid resistant steels. Also work very well on standard metals steels, RSG, aluminium, high temperature alloy, titanium alloy, non ferrous metals, plastics and wood.

Notes - Choose the right lubricant can facilitate cutting or cooling, make cutting easier, and improve dimensional accuracy. Please pay attention to the speed adjustment when using the electric drill. The larger the drilling size, the slower the speed requirement.

Wide Applications The drill bits can drill clean and accurate holes in stainless steel, cast iron, A3 steel, carbon steel, aluminum alloy, copper, wood and plastic. Sharp cutting edges provide neat and smooth cuts. Large spiral grooves facilitate the export of metal chips.
