Drill Bit MODECO MN-61-954 SDS‑MAX 20 mm, set of 10

Set of 10 MODECO SDS‑MAX drill bits, each with a 20 mm diameter, designed for use with SDS‑MAX rotary hammers. These drill bits are intended for drilling larger bore holes in concrete, reinforced concrete, masonry and other hard mineral materials. The set provides a consistent 20 mm hole size across ten pieces, ensuring repeatable results for jobs that require multiple identical holes.

Advantages

The MODECO SDS‑MAX 20 mm drill bit set offers compatibility with SDS‑MAX chucks for secure, impact‑resistant connection and efficient power transfer. Manufactured for heavy‑duty drilling, the bits are balanced for reduced vibration and designed to maintain cutting performance under prolonged use. Having ten identical bits in one set reduces downtime for replacing worn bits on site and ensures consistent hole geometry for anchor installation and conduit passage.

Suitable for

• Drilling 20 mm holes in concrete and reinforced concrete
• Creating anchor and dowel holes in masonry
• Preparation of through‑holes for plumbing or electrical conduits
• Professional construction and renovation projects requiring larger bore holes
• DIY tasks involving heavy‑duty drilling in hard mineral materials

Key specifications

• Shank system: SDS‑MAX compatible shank for rotary hammers
• Diameter: 20 mm nominal cutting diameter
• Quantity: set of 10 identical drill bits
• Intended materials: concrete, reinforced concrete, masonry and similar hard mineral substrates
• Use type: percussion/hammer drilling with rotary hammer

How to use

Install a MODECO SDS‑MAX 20 mm bit into the rotary hammer's SDS‑MAX chuck until it locks in place. Select an appropriate drilling speed and hammer setting according to the rotary hammer manufacturer's recommendations for 20 mm carbide bits. Begin drilling with steady axial pressure; avoid excessive side load to prevent bit breakage. For deep holes, periodically withdraw the bit to clear dust and debris, improving cutting efficiency and cooling the flutes. Use appropriate personal protective equipment including eye and hearing protection and a dust extraction or mask when drilling mineral materials.

Usage recommendations

For best results when drilling reinforced concrete, use intermittent drilling with periodic cleaning of the hole and allow the bit to cool. Match drill speed and hammer energy to the substrate hardness and replace bits from the set as they wear to maintain hole quality and drilling efficiency.
