Spotting Drill Bits
-
Product Highlights- Diamond tipped drill bits: electroplated diamond is uniform and more wear-resistant. the hole saw achieves high precision and smooth cuts without edge breakage, with good toughness and high strength.
- Sharp & smooth cut: diamond hole saw creates high precision, smooth cuts with no broken edges. white zinc plating on the bits maximizes tool’s life with great resistance to corrosion
- Specification: size: 110mm / 4.33". suitable for cutting accurate holes on glass, ceramic, tile, porcelain, marble, stone bottles and pots. the spotting drill bit in the center helps for cutting accurate holes
- Large clearance hole: the diamond hole saw with clearance hole facilitates the entry of cooling water and the escape of chips from the drilled hole. makes the drilling process easier. the cutting is flat and smooth without scratches.
- Tips: please use at low drill speeds and drill pressure. always work with coolant (water) when drilling. not suitable for drilling tempered glass, plastic and wood. not suited for use on concrete or for depths beyond about 1/2".

Product Highlights
- Wide applications: widely used for drilling steel below hrc60, such as stainless steel, carbon steel, die steel, alloy steel. the altisin composite coating has high hardness, high wear resistance and high thermal stability.
- Easy to use: universal chamfered round shank, easier clamping, stable cutting process. suitable for cnc machining centers, cnc machine tools, precision engraving machines and other equipment. the longer the length of the tool clamped by the chuck, the better.
- Spotting drill bits: cutting edge diameter: 6mm / 0.24"; shank diameter: 6mm / 0.24"; point angle: 90 degree; total length : 50mm / 2.0". large spiral flutes provide neat and smooth cuts. spiral groove facilitates the export of metal chip.
- Carbide tool: made of fine-grained tungsten carbide, the drill bit has good toughness, high hardness (hrc92), wear resistance and heat resistance. with good cutting strength and drilling effect, carbide tool offers long tool life and faster cutting speeds than other substrates.
- Tips: if the clamping length is shorter, you need to lower the feed rate and cutting speed to reduce vibration and extend the tool life. select an appropriate feed rate and cutting speed to improve the tool life and obtain better processing accuracy and performance.
