Drill Bit MEGA SDS+ 10 mm model 81021 for rotary hammers, carbide tip

MEGA SDS+ 10 mm drill bit model 81021 is designed for use with SDS+ rotary hammers to drill into masonry, concrete and natural stone. The bit has a 10 mm working diameter and an SDS+ shank that provides secure, rapid tool engagement and reliable torque transfer during hammer drilling. A carbide/reinforced tip improves wear resistance and cutting performance when penetrating hard substrates commonly encountered in construction and renovation work.

Advantages

The SDS+ connection ensures fast insertion and removal with minimal play, reducing wobble and improving hole accuracy. The carbide tip enhances durability and maintains cutting edge under repeated impact drilling. The 10 mm diameter offers a practical balance between hole size and drilling speed, suitable for anchor bolts, cable routing and fixing points. Designed for rotary hammer use, the bit withstands combined rotation and percussion forces.

Suitable for

• Drilling anchor and fixing holes in concrete and masonry
• Creating passages for cables and pipes in walls and floors
• Installation and renovation tasks requiring reliable hammer drilling
• Work where a carbide tip is needed for longer life in abrasive materials

Key specifications

• Shank system: SDS+ for rotary hammers
• Working diameter: 10 mm
• Tip type: carbide/reinforced tip for improved wear resistance
• Application materials: masonry, concrete, natural stone
• Intended use: hammer drilling with rotation and percussion

How to use

Insert the SDS+ shank into the rotary hammer chuck until it locks; verify secure engagement before starting. Select an appropriate drilling speed and hammer setting for concrete or masonry. Apply steady axial pressure without excessive force; allow the tool and carbide tip to do the cutting. Periodically withdraw the bit to clear dust and debris for deeper holes. After use, clean the flutes and tip to remove residue and store the bit in a dry place.

Usage recommendations

Use personal protective equipment such as safety glasses, dust mask and hearing protection. For best results, match the hammer power and setting to the material hardness, and replace the bit when cutting performance noticeably decreases.
