- Black gold high speed steel is the long lasting material when it comes to common drill bit materials, not only will the bit's structural integrity withstand tremendous heat and wear, but more importantly black gold bits can drill through tougher materials than common HSS bits.
- With a 135 degree split-point, these drill bits will catch on the work-surface with greater ease and not wander all over the surface making scratch-marks. This means that after securing the bit in the machine all that is needed is a steady hand to point and apply pressure, and that's it.
- The 3-Flat shank of our bits means you can use this drill bit with nearly all types of machines.
- The jobber length is the most commonly used length to diameter standard of drill bit in the US, the length is scaled according to the diameter of the drill head to give maximum force with maximum support so as to keep the bit from bending under the pressure, all the while keeping the machine a comfortable distance from the surface so as not to come in contact and scratch it.
- Included in the package is 12 pieces. Making for a total of 12 drill bits in total. This dimension in a plastic pocket (pvc pocket), this style of packaging keeps waste low and remains the simplest way to keep this many bits clean, out of the dryness or wetness of the air.

uxcell 12pcs Jobber Drill Bits 2.5mm (0.098") Black Nitride & Gold Titanium Coated M2 High Speed Steel (HSS) Twist Drill Bits for Stainless Steel Aluminum Alloy Metal
Brand: uxcell

- Twist Drill Bits: Cutting edge diameter: 2.5mm / 0.098"; round shank diameter: 2.5mm / 0.098"; cutting edge length: 30mm / 1.18"; overall length: 57mm / 2.24"; split point: 135 degree. Used with hand drills, drill presses, bench drills, machining centers, CNC lathes, etc.
- M2 High Speed Steel: M2 high speed steel (HRC64-66) drill bits offer excellent heat resistance and hardness for durability and longevity, as well as good cutting performance and accuracy for clean, precise holes with minimal burrs.
- Black & Gold Finish: Black nitride and gold titanium dual coatings can apply lubricant better for smoother drilling and are more durable and corrosion resistant. Sharp cutting edges provide neat and smooth cuts. Large spiral grooves facilitate the export of metal chips.
- Wide Applications: Drill bits produce holes in stainless steel, cast iron, A3 steel, carbon steel, aluminum alloy, copper, wood and plastic. Most suitable for drilling metals with a hardness less than HRC38, and cannot drill quenched metals, tiles, concrete, walls, stones.
- Tips: Use an appropriate lubricant to reduce friction and heat build-up. Controlling the speed is very important, recommended speed: 100-800rpm/min. The larger the diameter, the slower the speed required. If the hole is larger than 6mm, first drill a small hole with a 3.2mm-4mm drill bit, and then use a larger drill bit to enlarge the hole.
