Drill bit for concrete MEGA SDS+ 20 mm model 82045

MEGA SDS+ 20 mm drill bit model 82045 is a rotary hammer accessory designed to create clean 20 mm diameter holes in concrete and masonry. Engineered for SDS+ chucks, the bit delivers targeted material removal for anchor and dowel installation, electrical conduit routing, and general construction drilling. The carbide tip and flute geometry are optimized to maintain drilling speed and reduce clogging when penetrating dense substrates on job sites and renovation projects.

Advantages

This 20 mm concrete drill bit offers consistent hole diameter and stable drilling performance in reinforced and non-reinforced concrete. Its SDS+ shank enables secure, tool-free insertion and reliable power transfer from rotary hammers. The tip geometry improves breaking and removal of material while the spiral flutes evacuate dust efficiently, reducing the need for frequent pull-outs and speeding up repetitive drilling tasks.

Suitable for

• Drilling holes in concrete and masonry for anchors and dowels
• Creating passages for electrical and plumbing conduits
• Fixing heavy fixtures to walls or ceilings during construction or renovation
• Preliminary drilling for rebar location and anchor setting

Key specifications

• Drill diameter: 20 mm
• Shank type: SDS+
• Primary material: carbide-tipped cutting head with hardened steel body
• Intended use: rotary hammer drilling in concrete and masonry
• Flute design: spiral for dust evacuation

How to use

Insert the SDS+ shank into the rotary hammer chuck until it locks, ensuring the tool is disconnected from power during mounting. Select hammer-drill mode on the rotary hammer and apply steady axial pressure while allowing the tool to do the cutting. Periodically withdraw the bit to clear accumulated dust from the hole and maintain drilling efficiency. When drilling near reinforcement, proceed slowly and reduce feed pressure to avoid sudden bit deflection.

Usage recommendations

For optimal life and performance, use the bit in hammer mode with SDS+ rotary hammers at recommended speed settings for concrete. Keep the bit straight during operation, avoid excessive lateral force, and clear debris regularly. Replace the bit once the carbide tip shows significant wear or if drilling slows markedly.
