SAIBOO Hole Saw Carbide Drill TCT Metal Hole Saw Drill TCT Drill Hole Saws with Pilot Drill for Holes in Stainless Steel, Mild Steel, Alloy, Iron, Aluminum, Copper, Brass (29mm)

• Sharp cuts: the TCT metal hole saw drill is made of a high-strength alloy and has an innovative three-blade design (outer, middle and inner blade), which allows high-precision cuts, sharper cuts and smooth edges
• Stepped guide drill: the stepped structure of the pilot drill allows precise positioning and prevents slipping when drilling, while the natural damping and slowdown when penetrating the material reduces immediate impact and reduces breakout
• Efficient chip removal: special arc-shaped chip removal groove design, with ejector spring device, can automatically dissipate the waste material when drilling to achieve quick chip cleaning and effectively avoid clogging of the cutting edges
• Multi-scenario application: hole saw carbide drill can easily cope with all kinds of metal processing needs, such as copper and aluminium cutting, pipe opening, cast iron repair and sheet metal parts processing, etc
• Instructions for use: When drilling with a hand drill, keep the machine quiet so that the hole saw is vertical to the workpiece. Do not shake left and right, first slowly and then quickly, otherwise the blade will break easily

Hole Saw Carbide Drill Bit - Professional Solution for Drilling Metal Materials Size: Cutting Diameter 29mm Cutting Depth 25mm Shank Diameter 10mm YG8 Tungsten Carbide The metal hole cutter is made of solid YG8 carbide. Once molded, durable. Multi-tooth design. The TCT metal hole saw drill is equipped with multiple cutting teeth that drill holes with low resistance, quickly and burr-free. Anti-drift design. The pilot drills and bits use improved centring technology to effectively prevent deflection and runout errors. Multi-purpose. The metal hole saw drill is ideal for processing stainless steel plates, steel, cast iron, aluminium alloys, copper, steel plates, iron plates, aluminium plates, wood and other materials. Note: Not suitable for concrete, tile, glass or stone. How to use: The speed and torque of the cordless drill are low, so that the drilling capacity cannot be fully exploited. It is recommended to use a powerful hand or bench drill. The power of the hand drill must be over 750W. Impact drills are not permitted. Keep the drill bit evenly and at low speed to extend the life of the hole opener. When processing stainless steel and steel plates with a thickness over 5 mm, please add coolant or cutting oil.
