Sealey Masonry Drill Bit Set - 15pc - AK3715M

These Sealey masonry drill bits are designed for use on common masonry materials such as brick, concrete, stone, mortar, and plaster.

Select the drill bit size based on the diameter of the screw, anchor, or bolt you intend to use. Check the recommended hole size specified by the manufacturer of the fastener or anchor.

Yes, you can use them with a standard rotary drill, but the cutting action will be significantly slower and less efficient compared to using a drill with a hammer or percussion function on masonry.

The set includes three 3mm, three 4mm, three 5mm, two 6mm, two 8mm, and two 10mm drill bits.

Yes, the set comes in a durable plastic storage box with a rubberized, non-slip coating designed for secure handling and protection of the bits.

The drill bits are made from heavy-duty tungsten steel.

No, masonry drill bits do not require a 'break-in' period. They are ready for use straight out of the box.

Ensure the drill is set to the correct mode (hammer/percussion for masonry). Check if the drill bit is worn or damaged. Apply steady, consistent pressure and allow the drill to do the work. Clean any debris from the hole.

Reduce drilling pressure and speed. Withdraw the bit periodically to clear debris and allow it to cool. Consider using a cutting fluid or lubricant specifically designed for drilling into hard materials.

Avoid excessive force or jamming the bit. Ensure the hole is clear of obstructions. Use the correct bit size for the intended fastener or anchor. Allow the bit to cool if it becomes very hot.

Store bits in a dry environment. Clean off surface rust with a fine-grade steel wool or wire brush. Apply a light coat of oil to prevent future rusting.
