Micro PCB Drill Bits, 1/8" Shank 0.5mm Cutting Edge, Tungsten Carbide Print Circuit Board Drill Bit - (Applications: for CNC Drilling Engraving Machine), 1-Set (10-Pieces)

Attributes:* Cutting Edge Diameter (CED): 0.5mm / 0.02"* Cutting Edge Length: 7mm / 0.276"* Shank Diameter: 3.175mm / 1/8"* Overall Length: 38mm / 1-1/2"* Cutting Edge Material: Tungsten Carbide* Shank Material: HSS (High Speed Steel)What Is Included:* 1 Set (10 Pieces) x PCB Drill Bits, 1 Piece x Protective BoxApplications & Features:--- Widely used for drilling PCB (print circuit board), acrylic, plastics, aluminium, soft metal, fiberglass, wood, etc. Suitable for PCB drilling machines, engraving machines, CNC and high precision special drilling equipment. Use vertically and control your CNC speed well. Can work quickly and cleanly, no glitches or scrap left.--- Tungsten carbide bits have high hardness, good toughness, wear resistance, high strength, resistance to bending and heat resistance, providing a precise and easy experience. With good milling and engraving performance, carbide materials can run at higher speed than high-speed steel to ensure high work efficiency. Sharp cutting edge provides smooth drilling, low cutting force and drilling accuracy to prevent tool breakage. Large chip removal space, smooth chip removal, and low drilling heat. The positioning ring reduces machine set-up time and increase efficiency.Useful Tips:--- The mini drill bit is too tiny and easily twisted off. Be careful and control your CNC speed. The longer the chuck clamps, the better. If the clamping length is short, the feed rate and cutting speed should be reduced to reduce vibration and increase tool life.
