Product Details:
Twist Drill Bits Hss High Speed Steel Drill Bit is made of high speed steel raw material, delivers good hardness, wear resistance and heat resistance during high speed cutting. It can withstand frictional heat generated in continuous drilling work.
With Twist flute spiral groove design and Point angle standard geometry
Classic twist flute spiral grooves efficiently evacuate metal chips away from the drilling hole. Reduce bit jamming and overheating, bring smoother drilling performance. Standard drill point angle helps the bit self center on workpiece surface, prevents wandering or slipping when starting drilling.
- Wide material compatibility: Mainly for drilling general purpose ferrous and non ferrous metals: mild steel, iron sheet, aluminum, copper. Also works on plastic, PVC, thin hardwood. (Note: Not suitable for hard alloy steel, stainless steel heavy‑duty drilling, concrete, tile or stone.)
- Uniform surface finish treatment: Common surface options: bright polished, black oxide, titanium coated. Coated versions further improve surface hardness, anti-wear and service life.
