HSS Drill Bits

This High-Speed Steel (HSS) drill bit set offers reliable precision for home maintenance, fabrication, and technical workshop applications. Each bit features standard cylindrical straight shanks that fit smoothly into keyless and keyed drill chucks alike. The precision-ground spiral flutes eject shavings efficiently, lowering friction and mitigating heat build-up during extended operation.
The compact, transparent plastic housing protects the cutting edges against moisture and impacts, allowing instant visual verification of sizes.

Type: Standard manufacturer limited warranty covering workmanship and material defects.
Coverage Scope: Covers structural flaws (e.g., casting defects) under intended operating conditions.
Exclusions: Excludes normal wear and tear, dulling through continuous heavy usage, improper application (e.g., use on masonry/concrete), or breakage caused by excessive side-torque.

Q1: Can these drill bits be used on stainless steel?
A: Yes, HSS bits can process softer or light-gauge metals. However, for high-frequency or thick-gauge stainless steel, using low drill speeds with a dedicated cutting fluid/lubricant is recommended to prolong bit life.
Q2: Will these fit standard electric and cordless drills?
A: Absolutely. Their standard straight shanks are universally compatible with standard 1/4-inch, 3/8-inch, and 1/2-inch drill chucks.
Q3: What maintenance keeps these bits sharp?
A: Apply a drop of cutting fluid during heavy metal drilling to reduce heat. Wipe off residual debris after use and store the bits in their protective plastic case.
