Drill bit EPM for aerated concrete Ytong 50 mm, model E-326-2050

The EPM drill bit for aerated concrete Ytong 50 mm (model E-326-2050) is designed to produce clean, precise circular holes in lightweight concrete blocks and aerated masonry. Made for use with compatible rotary or percussion drills, this 50 mm diameter bit enables straightforward preparation of blockwork for installations such as anchors, pipe penetrations and electrical conduits. The geometry and cutting edges are tailored to minimise material chipping and to maintain hole roundness in cellular concrete materials.

Advantages

This drill bit offers consistent hole diameter and smooth cutting performance in aerated concrete, reducing the need for secondary finishing. Its tip and flute design aid dust removal and lowering drilling resistance, which helps preserve drill motor life and operator control. The 50 mm size is a common choice for many installation tasks, delivering sufficient clearance for pipes and anchors while keeping the hole clean and accurately centred.

Suitable for

• Drilling clean holes in aerated concrete blocks (e.g., Ytong) for pipe and conduit passage
• Preparing holes for chemical or mechanical anchors in lightweight masonry
• Creating openings for ventilation ducts, cable entry points and fixture installations
• General blockwork preparation when installing plumbing, electrical or HVAC components

Key specifications

• Drill bit type: for aerated concrete / masonry
• Diameter: 50 mm
• Intended material: autoclaved aerated concrete and lightweight blockwork
• Suitable drill modes: rotary and light percussion (depending on manufacturer guidance)
• Cutting geometry: tip and flute design optimised for reduced chipping and chip extraction

How to use

Select a drill with sufficient torque and suitable chuck to accommodate the 50 mm bit. Mark the drilling point on the block, clamp or steady the workpiece if possible, and position the bit perpendicular to the surface. Start drilling at low speed to establish the pilot engagement, then apply steady pressure and increase speed as appropriate for the drill and material. Periodically withdraw the bit to clear dust and improve cooling. If using percussion mode, keep impacts moderate to avoid excessive vibration that could damage fragile aerated blocks.

Usage recommendations

Use appropriate personal protective equipment — safety glasses, dust mask and hearing protection. For best results, combine the drill bit with a compatible drill that provides stable speed and torque. When installing anchors or pipes, check hole depth and clean out dust before inserting fixings to ensure proper bonding and secure fit.
