Product Description

Solide Carbide Twist Drills for machining

The solid carbide drill bits on the market are generally monolithic drill bits made of tungsten steel. Although the materials are the same, due to the processing technology, the quality of each brand's products is very different. Imported and domestic alloy drill bits also vary widely.
Imported alloy drills typically use VHM micro-grain hard alloys (ISO K40), ultra-fine particle types (0.6µm) ideally combine hardness and toughness in high performance drills and conventional milling applications.
The surface of high-quality alloy drills will be coated, such as aluminum-chromium (AlCrN) coating, which is a single-layer coating with a thickness of 4 μm, a microhardness of 3200 HV, a friction coefficient of 0.35, and a thermal stability of 1100. Celsius. The color of the drill bit is blue-gray after coating.
After coating, the alloy drill bit can process low alloy steel and high strength steel. High-hard steel can reach 54HRC.

Characters and advantages of products:
1 high precision
2 high efficiency
3 all the cutting tools quality meet the ISO international standard.
4 high strength and high hardness, hard-wearing
5 competitive price
6 fast delivery

Deep hole drilling consists of drilling andgun drilling with additional processes designed for specific tolerance objectives and generally performed on BTA-style deep hole drilling machines. Deep hole drilling is used in a variety of materials from aluminum to super-alloys, and is capable of achieving tight diameter control, straightness, and superior surface finish into workpieces.
