Material: tungsten steel base material

Suitable for processing: fixed point positioning + chamfering processing

Angle: 90°

Hardness: HRC55°

Recommendation: for uncoated aluminium/coated steel

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

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

Quality optimization: General tungsten steel has a number 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 the starting hole with a depth of 1-2 times the diameter to ensure the drilling accuracy with a conventional drill.
Chamfer reserve for threading for easier threading. (This centering drill can only be rolled, 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 upper angle of the micro drill of the end hole (if the upper angle of the centering drill is small, when cutting into the micro drill, two
cutting edges contact the workpiece in front of the center, which makes it easy to roll the tool)
