Product Specification: Material: Stainless tungsten steel, and alloy. Drill type: Alloy triangle bit Handle type: Triangle handle Outsizediameter:16mm/0.62'',18.5mm/0.73'',20mm/0.78'',25mm/0.98'',30mm/1.18’' Chuck size: 10mm Total length: 65mm/2.55'' Quantity: 6pcs assorted in a portable storage case DURABLE MATERIAL: High Speed Steel and allay steel, with high hardness, high wear resistance, high strength, resistance to bending, anti-impairment and long tool life, fatigue resistance and higher wear resistance. Glass and tile drill bits provide smooth, accurate drilling in ceramic tile, marble, mirrors and glass. Drill has a large scraps discharge space,little resistance and smoothly during the Using high quality materials and fine grinding process makes bit more sharp cutting edge,reduce cutting force and broken drill and improve the quality of hole wall. CHARACTER: ● The toothed design makes cutting faster and saves time and effort. ● Each edge is a part of the characteristics of the cutting work, making the hole is not easy to produce the phenomenon of collapse. ● Sharp head of blade. The chips are smooth and burr-free, and the chip groove are uniquely designed for unobstructed chip evacuation. non-slip, anti-shedding, can easily replace the drill. ● It widely used in wood, PVC pipe, plastic, plaster, like home bedroom, wall surface, glass wall edge, kitchen, kitchenware, sink edge, acrylic words on the facade outdoor , etc. Package including: 16mm (0.63 inch - 1PCS), 18.5mm (0.73 inch - 1PCS) 20mm (0.79 inch - 1PCS) 25mm (0.98 inch - 1PCS) 30mm (1.2 inch - 1PCS) 5 x Wrench Packing: 5pcs ( 1pcs for each Value ) 1 x Plastic boxes

• Different Size: 16mm/0.62'',18.5mm/0.73'',20mm/0.78'',25mm/0.98'',30mm/1.18'', interval for each specification), total length 65mm/2.55''.
• Cutting edge strictly symmetrical: Surface anti-rust treatment, smoother drilling and chipping.beneficial and efficient cutting, avoid offset drilling. Big space for chip removal, big space for chip removal, the chip resistance is small, the chip discharge is smooth, the heat generated by the hole is small, and the drilling is reduced.
• Extraordinary cutting edge sharpness: high temperature quenching to improve hardness. The cutting edge of the drill bit is sharper than before, which can reduce the cutting force, reduce the drilling rate and improve the quality of the hole wall.
• Made tungsten carbide bits, Using hard alloy (tungsten steel) material, with high hardness, high wear resistance, high strength, bending resistance, resistance to damage and other characteristics, complete specifications.
• Fit for: There are a wide variety of drills to meet different application needs. All parameters of the milling cutter, such as core thickness and core taper, have been carefully designed and effective. Perfect for Installing Locks, Knobs in Doors and Cabinets or Drilling Larger Diameter Holes Through Desks Etc
