Drill Bit Set Work-it 56312 — 5-piece Concrete Masonry Bits

Work-it 56312 is a 5-piece concrete masonry drill bit set intended for drilling into concrete, brick and natural stone. Each bit is made in the SDS-plus style for use with rotary or hammer drills that accept SDS-plus shanks, allowing faster tool changes and stable seating during percussion drilling tasks. The set covers common hole sizes for anchor fixing, conduit installation and other general masonry work.

Advantages

The set provides a compact selection of SDS-plus bits optimized for percussion drilling in hard substrates, reducing the need to switch between incompatible shank types. Hardened carbide tips increase durability and sustain cutting performance in abrasive materials. The consistent shank type ensures compatibility with SDS-plus chucks, offering quick bit changes and stable drilling under hammer action.

Suitable for

• Drilling holes for chemical and mechanical anchors in concrete and masonry
• Installing electrical conduits and plumbing sleeves through brick or block
• Creating starter holes for anchors or dowels in stone and natural rock
• General repair and renovation tasks requiring percussion or rotary hammer drilling

When it may not be suitable

This drill bit set is intended specifically for concrete and masonry applications. It is not designed for efficient drilling in metal or wood, and performance will be poor or cause premature wear if used on such materials. The SDS-plus shank requires a compatible drill; it will not fit standard straight-shank chucks without an adapter.

Key specifications

• Number of pieces: 5
• Shank type: SDS-plus
• Intended materials: concrete, brick, natural stone
• Tip material: carbide-tipped for masonry cutting
• Use mode: rotary and rotary hammer (percussion) drilling

How to use

Select a bit size appropriate for the anchor or fixture, mount the SDS-plus bit into a compatible rotary hammer or hammer drill until it locks, and set the tool to percussion mode for concrete and masonry. Drill at moderate feed pressure, allowing the carbide tip to cut and the hammer action to break out material; withdraw occasionally to clear dust. For through-holes, mark both sides if needed and start with a pilot position. After drilling, clean the hole with a brush or compressed air before inserting anchors or conduits.

What to consider before purchase

• Ensure your drill accepts SDS-plus shanks or plan to use an appropriate adapter
• Confirm the included bit sizes match the anchor or fixture diameter you will use
• Check that you need bits optimized for masonry rather than for wood or metal

Usage recommendations

Use steady, moderate pressure and let the tool’s hammer action do the work; avoid excessive side loads to prevent bit breakage. Keep drilled holes clear of dust for secure anchor installation, and replace heavily worn bits to maintain drilling efficiency and safety.
