Product Description

"SDS STEP BIT" refers to a specialized type of drill bit combining two features:

  1. SDS Shank: This is a quick-change chuck system (SDS-Plus or SDS-Max) primarily used with rotary hammer drills. The shank has grooves that lock securely into the drill's chuck, allowing for hammering action and easy bit changes without needing a chuck key. SDS drills are essential for drilling into hard materials like concrete, brick, and stone.

  2. Step Drill Bit: This is a conical-shaped bit with progressively larger diameters (steps) along its length. A single step bit can drill multiple hole sizes without needing to change bits. They are primarily designed for drilling clean, burr-free holes in thin sheet metal, plastic, and sometimes wood.

The Key Point: Incompatibility for Hammering

  • Standard step drill bits are NOT designed for hammer action. They are cutting tools made for metal/plastic/wood. Using a standard step bit in a rotary hammer (SDS drill) set to hammer mode will destroy the bit almost instantly and could damage the drill or cause injury.

  • Step bits require rotary cutting action only (like a standard drill/driver).

When "SDS STEP BIT" Might Exist (Specialized Application):

  • Masonry Step Core Bits (Rare): There are specialized core bits designed for drilling large holes in masonry that might have:

    • An SDS shank.

    • slightly stepped profile (e.g., for drilling through pipes embedded in concrete where you need a larger hole on the surface).

  • Misinterpretation: Sometimes people might see a large masonry bit with an SDS shank and describe its appearance as "stepped," but it's not a true step bit for metal cutting.

Common & Correct Uses:

  1. SDS Bits: Used exclusively with SDS rotary hammers for drilling into masonry/concrete. Common types are:

    • SDS-Plus Drill Bits (4-12mm typical)

    • SDS-Max Drill Bits (12mm+)

    • SDS Chisels (Point, Flat, Scutch)

    • SDS Core Bits (for large holes)

  2. Step Drill Bits: Used exclusively with standard drills/drivers (NO HAMMER FUNCTION) for drilling clean holes in sheet metal, plastic, and thin wood.

In Summary:

  • A standard "SDS Step Bit" for cutting metal with hammer action does not exist and is a dangerous misuse of tools.

  • SDS rotary hammers use specialized masonry drill bits and chisels.

  • Step drill bits are used only in standard rotary drills/drivers for metal/plastic/wood.

  • If you need a large hole in masonry, use an SDS core bit with the correct shank (SDS-Plus or SDS-Max).

  • If you need multiple hole sizes in metal, use a standard step drill bit in a regular drill/driver.
