Drill America

Drill America SDS3818 3/8" x 18" SDS-Plus Hammer Bit

SKU CH-0ZCP-JVM6H

An SDS-Plus hammer bit with a carbide tip for drilling stone or concrete, auto-welded on German and Swiss equipment with a Japanese carbide tip

  • 3/8-inch SDS-Plus shank fits rotary hammer drills
  • 18-inch overall length reaches deep into concrete or stone
  • Carbide tip welded on German and Swiss equipment resists wear
  • Steel shank adds toughness for heavy-duty drilling
  • Meets California Proposition 65 chemical disclosure requirements

Application Scope

This SDS-Plus hammer bit is built for drilling stone or concrete with rotary-hammer tools. It serves tradespeople and serious DIY users who need a durable accessory for masonry work.

Critical Specification

The bit uses a 3/8 inch diameter and an 18 inch overall length, dimensions that determine whether it reaches the required depth and fits the anchor or fastener specified for the job.

Build Integration

The SDS-Plus shank locks directly into compatible rotary hammers without a separate chuck, freeing the user from keyed-chuck slippage. Carbide tips welded on German and Swiss equipment resist wear in abrasive aggregate, while the steel shank absorbs impact energy. California Proposition 65 warnings apply.

Questions about this item

What does the 18-inch overall length mean when the bit is chucked into an SDS-Plus rotary hammer?

The 18-inch length provides a usable drilling depth of roughly 18 inches minus the chuck engagement, so you can reach deep holes in concrete or stone without an extension.

How does the SDS-Plus shank limit what this bit can do compared with a plain round shank?

The SDS-Plus shank locks into the hammer's chuck for positive rotary and hammer drive, but it will not fit a standard three-jaw drill chuck without an adapter.

What clearance is needed behind the tool for the 18-inch bit to fit during use?

You need at least 18 inches of free space behind the rotary hammer plus room for the operator's hands to accommodate the full bit length.
