SDS Max Drill Bit - 38mm x 370mm

This drill bit requires a rotary hammer drill equipped with an SDS Max chuck system. It is not compatible with standard drills or SDS Plus rotary hammers.

This drill bit is primarily designed for drilling into masonry materials such as concrete, brick, and stone. It is also suitable for other hard building materials.

Insert the SDS Max shank fully into the chuck until you hear or feel a click. A slight rotation of the bit while inserting may be necessary to engage the locking mechanism within the chuck.

SDS Max is a larger, more robust system designed for heavy-duty rotary hammers, offering greater power transfer and durability. SDS Plus is a smaller system for lighter-duty rotary hammers.

Clean the bit after each use to remove dust and debris. Store it in a dry environment and inspect it for wear or damage. Replace the bit if the cutting edges are significantly worn or damaged.

While robust, this bit is primarily for concrete and masonry. Drilling through reinforced concrete containing significant rebar may cause excessive wear or damage. For rebar, specialized drilling techniques or bits might be necessary.

Ensure the chuck is clean and free of debris. Verify that you are using an SDS Max chuck and that the bit's shank is fully inserted and rotated slightly to engage the locking grooves.

Check if the drill's hammer function is engaged. Ensure the drill bit is properly seated and not worn out. Reduce pressure slightly and allow the drill's impact mechanism to work. Clean dust from the hole frequently.

This may indicate a worn chuck, a damaged drill bit shank, or improper seating. Remove the bit, inspect both the bit and chuck for damage or debris, and reinsert securely.
