3-piece step drill bit set

This K-Tool International KTI71233 set contains three step drill bits designed for creating multiple hole sizes with a single tool. It suits mechanics, fabricators and DIY users who need to drill through thin metal, plastic or wood without changing bits. The transparent colour helps identify the set quickly in a busy toolbox. First listed by the manufacturer on February 14 2025.

Bundled accessories and software

The package includes only the three step drill bits themselves; no case, lubricant, pilot drills or depth stops are supplied. Because no accessories are bundled, users must provide their own cutting fluid and workpiece clamping. There is no software component associated with this hand-tool product.

Compatibility checklist

Verify that your drill chuck accepts the shank diameter of these bits before ordering. Confirm the maximum material thickness you intend to drill matches the stepped profile length of each bit. Ensure you have appropriate cutting fluid and personal protective equipment for the materials you plan to work with.

Questions about this item

Will the 3-piece set need individual bit replacements as the cutting edges wear?

Each step bit is made from hardened steel so the cutting edges stay sharp through repeated drilling; replace a single bit only if it is damaged or the steps no longer match the hole sizes you need.

What limits continuous use before the bits overheat?

Heat builds fastest when drilling thick metal without lubricant; using cutting oil and clearing chips every few seconds keeps the tips cool enough for extended sessions.

How much noise and heat should I expect when running the bits all day in a hand drill?

The bits themselves run quietly; noise comes from the drill motor and material contact, while heat stays low if you apply steady pressure and cutting fluid rather than forcing the feed.
