Drill Bit Makita SDS‑MAX 16 mm for Concrete, model MA-D-33934

The Makita SDS‑MAX 16 mm drill bit (model MA‑D‑33934) is engineered for rotary‑hammer drilling in concrete and masonry. It features an SDS‑MAX shank for secure tool engagement and is designed to deliver efficient dust removal and stable drilling when creating 16 mm diameter holes in reinforced and non‑reinforced concrete. The bit is intended for use with compatible SDS‑MAX rotary hammers and is suited to tasks such as anchor installation, rebar pre‑drilling and general heavy‑duty construction drilling.

Advantages

This SDS‑MAX 16 mm concrete drill bit offers reliable connection to SDS‑MAX chucks, consistent hole quality and enhanced debris evacuation during drilling. Its design reduces bit wobble and helps maintain drilling speed in dense masonry. The robust construction improves durability under frequent use in professional settings and supports repeated drilling of 16 mm holes with predictable results.

Suitable for

• Drilling 16 mm holes for anchor bolts and chemical anchors in concrete
• Pre‑drilling for rebar installation and dowel placement
• Heavy‑duty construction and renovation work involving concrete and masonry
• Use with compatible SDS‑MAX rotary hammers on construction sites

Key specifications

• Drill bit diameter: 16 mm
• Shank type: SDS‑MAX for rotary‑hammer compatibility
• Intended material: concrete and masonry
• Primary applications: anchor and rebar pre‑drilling, heavy construction drilling
• Design features: optimized flute profile for dust removal and stable drilling

How to use

Install the drill bit into a compatible SDS‑MAX rotary hammer according to the tool manufacturer's instructions, ensuring the bit locks securely into the chuck. Position the bit perpendicular to the work surface, apply steady forward pressure and operate the tool in rotary‑hammer mode. Clear accumulated debris periodically by withdrawing the bit slightly while running, or by using a brush or air blower when appropriate. Follow recommended drilling speeds and feed rates for 16 mm holes in concrete to avoid excessive wear.

Usage recommendations

Use appropriate personal protective equipment: safety glasses, hearing protection and dust mask. For best hole accuracy, mark drilling points and use a guide or template if required. When drilling reinforced concrete, proceed with caution and reduce feed pressure when the bit contacts rebar, switching to suitable rebar drilling or cutting methods if necessary.
