The Simpson SDS-Plus Fixed-Depth Drill Bit for 1/2 in Short Drop-In Anchor DIAS is an SDS-plus shank drill bit engineered by Simpson to precisely prepare anchor sites for 1/2 in Short Drop-In anchors in normal-weight, sand-lightweight, and hollow-core concrete. Its fixed-depth design eliminates manual depth-setting, delivering a consistently sized hole every time so installers can focus on getting the job done right rather than double-checking their work.

Key Features

• Fixed-depth drilling - stops automatically at the exact required depth, removing guesswork and ensuring every anchor site meets installation requirements without additional measuring or setup.
• SDS-plus shank interface - provides tool-free bit retention and efficient rotary-hammer energy transfer, keeping the bit securely locked during operation for faster, more consistent drilling.
• Matched specifically to the 1/2 in Short Drop-In anchor (DIAS) - the bit diameter and drilling depth are calibrated precisely for this anchor type, so hole preparation is always correctly sized for reliable anchor performance.
• Approved for multiple concrete substrates - compatible with normal-weight concrete, sand-lightweight concrete, and hollow-core concrete, giving contractors flexibility across a wide range of common structural applications.

Why This Product

• Eliminates installation errors before they happen - because the depth is fixed and the diameter is pre-matched to the 1/2 in Short Drop-In anchor, there is no opportunity to drill too shallow, too deep, or at the wrong size, protecting the integrity of every anchor point.
• Engineered as a system, not a generic bit - Simpson designed this bit specifically for use with their own Drop-In anchor system, meaning the fit between the prepared hole and the anchor is exact rather than approximate.
• Speeds up repetitive anchor work - the fixed-depth stop and SDS-plus quick-release shank together reduce per-hole setup time on jobs requiring multiple anchor installations, keeping projects on schedule.
• Sourced from a quality-focused origin - this drill bit is produced in Germany, a country recognized for precision tooling manufacturing standards, consistent with the tight tolerances a fixed-depth anchor bit demands.

Frequently Asked Questions

What anchor is this drill bit designed to work with?

This fixed-depth SDS-plus drill bit is specifically designed to prepare anchor sites for the Simpson Strong-Tie 1/2 in. Short Drop-In anchor (DIAS). It is matched to that anchor's required hole diameter and embedment depth.

What hole diameter and drilling depth does this bit produce?

The MDPL062DIAS produces a 5/8 in. diameter hole at a fixed drilling depth of 1-1/16 in., precisely calibrated for the 1/2 in. Short Drop-In anchor installation requirements.

What concrete types is this drill bit compatible with?

This bit is suitable for use in normal-weight concrete, sand-lightweight concrete, and hollow-core concrete - the substrates for which Simpson Strong-Tie Drop-In anchors are approved.

What type of drill is required to use this bit?

This bit features an SDS-plus shank, which requires an SDS-plus compatible rotary hammer drill. The SDS-plus interface ensures secure bit retention and efficient energy transfer during drilling.
