QUARKZMAN 10-Piece 1.5 mm PCB Micro Drill Bit Set, 1/8 in Shank

Description

• Cutting diameter: 1.5 mm (0.059 in); shank diameter: 3.175 mm (1/8 in); overall length: 38 mm (1-1/2 in)
• Set includes 10 carbide micro drill bits with positioning rings
• Durable carbide construction with high hardness, toughness, wear resistance, strength, bending resistance, and heat resistance
• Spiral flute design improves chip evacuation, reduces cutting resistance and vibration, and supports stable cutting
• Suitable for jewelry, PCBs, plastics, fiberglass, acrylic, wood, aluminum, and other soft metals
• For PCB drilling machines, engraving machines, CNC lathes, machining centers, and most rotary tools with a 1/8 in shank
• Use the correct CNC speed and coolant or lubricant; keep the bit stable and perpendicular to the surface
• Store in a safe container to protect the delicate cutting edges; micro drill bits can break easily

This set contains 10 durable carbide micro drill bits for precise work on PCBs, jewelry, plastics, fiberglass, acrylic, wood, aluminum, soft metals, and other materials. The carbide material provides high hardness, toughness, wear resistance, strength, bending resistance, and heat resistance for efficient cutting. The spiral flute design helps evacuate chips, reduce cutting resistance and vibration, and support stable cutting. Positioning rings help reduce machine setup time. With a 3.175 mm (1/8 in) shank diameter, the bits fit most rotary tools. Use the correct CNC speed and coolant or lubricant to reduce friction and heat during drilling. Keep the bit stable and perpendicular to the surface, and store it safely to prevent damage to the sensitive cutting edges.
