20 mm x 400 mm SDS Drill Bit

This SDS drill bit is ideal for masonry tasks such as drilling into brick, concrete, and other hard masonry substrates. It’s not intended for metal or wood drilling.

This bit is designed for SDS-compatible hammer drills. Ensure your drill accepts SDS shanks and engage the chuck according to your drill’s manual for a secure fit.

To install: power off the drill, open the SDS chuck, insert the bit shank fully, and lock the chuck to secure it. To remove: switch off the drill, unlock the chuck, and pull the bit out straight from the chuck.

Use steady, controlled pressure with the drill in hammer mode. Start at a low speed to establish the hole, then gradually increase speed as needed. Periodically withdraw the bit to clear dust and prevent binding, and allow the bit to cool if it becomes overheated.

Keep drilling at appropriate speeds, avoid excessive pressure, and let the bit cool during longer sessions. Use in suitable masonry materials, use proper dust extraction if possible, and clean the bit after use to remove debris.

It’s well-suited for creating clean holes in masonry for anchors, wall plugs, conduit runs, and other fixings where a durable, vibration-tolerant bit is needed.

SDS drill bits come in different shank formats and sizes. SDS-Plus bits are typically for smaller-diameter, lighter-duty work, while SDS-Max bits handle larger diameters and heavier tasks. For a quick reference on Fepy, you can explore these alternatives: SDS-Plus Drill Bit 6mm (https://fepy.com/product/sds-plus-drill-bit-6mm) and SDS-Max Drill Bit 18mm (https://fepy.com/product/sds-max-drill-bit-18mm). You can also consider a general Masonry Hammer Drill Bit option like https://fepy.com/product/masonry-hammer-drill-bit-8mm for non-SDS tools.

Always wear eye protection, a dust mask or respirator, and hearing protection in noisy environments. Use gloves as needed, secure the workpiece, and use dust extraction if available to minimize airborne particles.

Store in a dry, clean location away from moisture. Inspect the bit for wear or damage before next use, and clean off any concrete dust or debris. Replace if the cutting edges are chipped or worn.

If drilling is slow or binding, ensure you’re using the correct diameter and in the right masonry, check that the drill is in hammer mode, and avoid excessive pressure. If the bit overheats, pause to cool and clean the hole. If the bit won’t seat properly, recheck the drill chuck and shank compatibility.

This SDS drill bit is designed for durability and reliable masonry performance, offering longer life under heavy use compared with basic bits. Its compatibility with SDS drills enables efficient impact drilling, contributing to faster project completion and overall value for professional or frequent DIY tasks.
