Special Features

  • Durability and Heat Dissipation: Made of tungsten steel material, enabling high-intensity drilling. The exceptional chip removal mechanism ensures high efficiency. The applied nano coating enhances its resilience and provides superior heat dissipation even at high speeds. In processes such as deep cavities drilling, fast drilling, spotting, holemaking, threading, slotting, plunging, form milling, and CNC metalworking, it performs excellently.
  • Precision Design and Manufacturing:precision these drills tolerance of less than -0.01mm (-.0004 inch). h6 shank tolerance for high precision tool holders ​. Its spiral twist design ensures efficient chip removal and superior hole quality. this drill bit delivers straight and accurate holes with a smooth finish. Suitable for both industrial and DIY projects, it provides reliable performance and longevity.
  • Wide Material Compatibility: specialized drill bit designed for deep cavity hole making.optimized for hardened steel, free machining steel, medium alloy steel, carbon steel, alloy steel, cast iron, tool steel, chrome nickel iron alloy, titanium alloys, inconel, nickel alloys, stainless steels and other high-temperature materials.(up to 55HRC)
  • High Speed and Smoothness: Uncoated,High helix for faster chip removal and better finish. The double margin design ensures exceptional hole accuracy and a flawless finish. The four-facet point eliminates the need for a pilot hole providing effortless drilling.
  • Drill Size:16.2mm Drill Dia.-80mm Max.Drilling Dp.-120mm OAL(.6377 Dia.-3.14 Max.Dp.-4.72 OAL inch)
  • Package:1pc,Multiple sizes and length to choose from, catering to different work requirements

Description

1.Guaranteed Quality:Our solid carbide drill bits are subjected to quality control tests before leaving the factory. Each Carbide Drill Bit is inspected under high magnification to ensure that it meets our stringent standards.
2.Solid carbide offer long tool life and faster drilling speeds than other substrates but more brittle.Make sure work piece and machine are stable use hydraulic chucks high quality collet chucks or shrink fit chucks.
3.Please adjust the speed feed and drilling depth according to actual drill conditions.Tool overhang please use the required amount of minimum size amount of long overhang is high vibration turn it to lower the number of feed when the tool overhang length is longer please adjust the speed.feed and cutting depth.
4.Adapt to several kinds of cooling conditions for example oil mist water oil air cooling.
