Carbide Spot Drill Bit 60 90 120 Degree CNC Drilling Guide Tool Location Center Router Bit Metal Drills Chamfer End Mill
Material: Tungsten steel base material

Suitable for processing: fixed-point positioning + chamfering processing

Angle: 60°/90°/120°

Hardness: HRC45°(uncoated)/HRC55°(coated: bronze)

Recommendation: For uncoated aluminum/coated steel

Applicable equipment: CNC machining centers, engraving machines, precision engraving machines and other high-speed machine tools. Positioning and centering work on NC and CNC machine tools. (It is not recommended to use a hand electric drill)

Suitable processing materials: copper, cast iron, stainless steel, die steel, aluminum alloy, etc.

Quality optimization: The overall tungsten steel has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance.

Note: 1. Before drilling, use a centering drill to drill an initial hole with a depth of 1-2 times the diameter to ensure the accuracy of drilling with an ordinary drill.
Reserve a chamfer for tapping to facilitate tapping processing. (This kind of centering drill can only be chamfered, not drilling) 2. The centering drill is suitable for high-speed and long-term drilling.
Dry processing, etc., and then do something before drilling. 3. The drill tip of the centering drill should be equal to or greater than the top angle of the micro drill of the final hole (if the top angle of the centering drill is small, when cutting into the micro drill,
The two cutting edges contact the workpiece in front of the center, which can easily cause the tool to collapse)
