Ideal for longer runs through walls and thicker sections, this is a practical choice for installers and trades who need reach, accuracy and consistent results.

SDS Plus Masonry Drill Bit 20mm x 1000mm 955427 – Key FAQs

  • What is this 20mm x 1000mm SDS Plus drill bit best used for?
    It’s ideal for deep drilling through masonry, block and concrete where long reach is required, such as service penetrations for pipes, cables and ducting runs.

  • Will this drill bit fit any SDS drill?
    It fits SDS Plus machines only. It will not lock into SDS Max or a standard 3-jaw chuck without the correct tool type and compatibility.

  • Can I drill concrete with this Silverline masonry bit?
    Yes. The tungsten carbide tipped head is designed for drilling into concrete and other mineral materials, delivering reliable cutting performance and durability.

  • Does the double-flute design make a difference?
    Yes. Double flutes help lift dust and debris out of the hole, reducing binding and helping you drill more smoothly particularly important on long, deep holes.

  • How do I drill deep holes without the bit jamming?
    Drill at a steady pace and withdraw the bit regularly to clear spoil. Avoid forcing the tool, and let the hammer action do the work to reduce snagging.

  • Is a 20mm masonry drill bit suitable for anchors and sleeve fixings?
    It can be, depending on the fixing system you’re using. Always match the anchor diameter and the manufacturer’s recommended drill size for the best hold and safety.
