Drill Bit MODECO SDS‑MAX 20 mm 10 pcs (MN-61-955)

Set of 10 MODECO SDS‑MAX drill bits with a 20 mm diameter, designed for use with SDS‑MAX rotary hammers. Each bit is made for drilling into concrete, masonry and other similar construction materials. The kit supplies multiple replacement bits for professional and DIY demolition, drilling and anchoring tasks and is suitable for extended on‑site work where reliable bit retention and repeatability of holes are required.

Advantages

The SDS‑MAX shank ensures secure engagement in compatible rotary hammer chucks, reducing slippage during heavy hammer drilling. A 20 mm cutting diameter provides a balance between bore size and material removal rate for anchor and through‑hole applications. Supplied as a set of 10 pieces, the pack offers immediate replacements to maintain productivity on site without frequent tool changes. The bits are manufactured to consistent dimensions to support accurate hole diameters and repeatable performance.

Suitable for

• Drilling anchor and through holes in concrete and masonry
• Making passage holes for pipes and conduits in structural walls
• Core starter holes for demolition and rebar location
• Repeated drilling tasks on construction sites and renovation projects

Key specifications

• Shank type: SDS‑MAX compatible
• Cutting diameter: 20 mm
• Quantity in set: 10 pieces
• Intended materials: concrete, masonry and similar mineral substrates
• Application: rotary hammer drilling with hammer action

How to use

Select an SDS‑MAX rotary hammer with the appropriate power and hammering mode for 20 mm drilling. Insert the bit into the tool’s SDS‑MAX chuck until it locks, ensuring proper engagement. Position the bit at the intended drilling point, apply steady axial pressure and allow the tool’s hammering action to advance the bit through the material. For clean, accurate holes pause periodically to withdraw the bit and clear debris. Replace worn bits from the set promptly to maintain hole quality and reduce stress on the tool motor.

Usage recommendations

Use suitable personal protective equipment including eye protection, hearing protection and dust mask. When drilling reinforced concrete, check for rebar and reduce feed force if the bit meets metal. Match drill speed and hammer settings to material hardness and choose fresh bits from the set for critical anchor holes to ensure correct fit and load capacity.
