Masonry Drill Bit Selection — Quick Reference
Masonry drill bits cut CONCRETE + BRICK + BLOCK + MORTAR + masonry. TUNGSTEN CARBIDE TIP welded to steel body. Hammer drill or rotary hammer required for efficient cutting — standard drill insufficient.
| Masonry Drill Type | Best For |
|---|---|
| TCT Masonry Drill (Standard) | Concrete + brick + block — hammer drill |
| SDS-Plus Masonry Drill | Rotary hammer drill — workshop standard |
| SDS-Max Masonry Drill | Heavy demolition rotary hammer |
| Diamond-Tipped Masonry | Reinforced concrete + harder material |
| Common Diameters (4-40mm) | Match to fastener / anchor |
| Set (Sizes 4-12mm typical) | Workshop range |
Critical: USE HAMMER DRILL or rotary hammer — standard drill won't cut efficiently + dulls bit fast. SLOW SPEED + steady pressure. Match shank type to drill chuck (standard / SDS-Plus / SDS-Max). PPE — eye protection + dust mask MANDATORY (silica dust). Brands: Sutton Tools, Bordo. Companion: drilling, concrete anchors, concrete screws.
Masonry Drill Bits
AIMS Industrial sells masonry drill bits & sets for drilling concrete, brick, block, stone and mortar joints. Our range from Sutton Tools, Bordo and Morris includes round-shank sets for hammer drills, SDS-plus sets for rotary hammers and extended-range sets for construction and civil applications.
Masonry Drill Types
- Round shank carbide tip: The standard masonry bit for corded and cordless hammer drills — carbide brazed tip with spiral flute for chip clearance in concrete and brick.
- SDS-plus masonry bits: Positive SDS-plus locking shank for rotary hammers — superior impact energy delivery compared to round shank bits in hard concrete drilling.
- Multi-purpose masonry bits: Cross-pattern carbide tips designed to cut in concrete, brick, tile and wood with a single bit — popular for trade renovation work.
- Percussion flat bits: Hardened flat tungsten carbide tip for heavy-duty breaker attachment — used for initial penetration in hard reinforced concrete.
- Set sizes: 5–6 piece sets (5–12 mm) for general trade use; 6–10 piece extended sets (5–16 mm) for construction and renovation with varied anchor sizes.
Drilling Performance Tips
- Hammer mode selection: Always use hammer or rotary hammer mode for masonry — rotation-only drilling destroys carbide tips and generates dangerous heat.
- Bit wear signs: Overheating (tip glowing) and loss of drilling rate indicate a worn carbide tip — a blunt masonry bit causes damage to both bit and surface material.
- Avoiding rebar: A reinforcement-detection scanner before drilling reduces the risk of hitting steel bars in concrete — carbide masonry bits cannot cut through rebar.
- Hole cleaning: Blow out masonry holes with compressed air before inserting anchors — dust and debris prevent full anchor expansion and reduce holding capacity.

People Also Ask — Masonry Drill Bit Sets
Q: What's a masonry drill bit?
A masonry drill bit has a tungsten carbide tip brazed to a steel shank, designed for cutting concrete, brick, stone, and other masonry materials. The carbide tip handles the abrasive nature of masonry that would dull standard HSS drill bits in minutes. Used with hammer drill function — the percussion action helps chip through the masonry while the rotation removes the chips. Common workshop sizes: 4mm-16mm. For larger holes: core drill bits or diamond cores.
Q: Hammer drill or standard drill for masonry?
Hammer drill: required for masonry drilling. The percussion mechanism delivers thousands of impacts per minute, breaking up the masonry while the rotation clears debris. Standard drill: doesn't have percussion, struggles to penetrate concrete or hard brick. Use only with extreme patience or for very soft mortar. For workshop daily masonry drilling: dedicated hammer drill is essential. For occasional masonry use: hammer drill function on combination drill works.
Q: What size masonry drill set covers most workshop needs?
Common workshop sets: 5-piece set (5mm, 6mm, 8mm, 10mm, 12mm) covers most household and light commercial wall mounting. 10-piece set adds 4mm, 7mm, 9mm, 14mm, 16mm — covers professional trade work. Premium sets include SDS-plus shank bits for SDS hammer drills (larger sizes). For workshop kit covering anchor installation: 6mm, 8mm, 10mm, 12mm are most-used. Add 16mm and 20mm for larger anchors.
Q: Standard or SDS shank masonry drill?
Standard shank (smooth or hex): fits any drill chuck via standard chuck. Common for small workshop hammer drills up to 16mm bit size. SDS-plus shank: dedicated SDS chuck (no chuck key, faster bit changes), better impact energy transfer to bit, suits SDS-plus rotary hammers. Standard for bits 6-25mm. SDS-max: even larger shank for heavy-duty rotary hammers (bits 16-50mm+). Match shank to your drill — they're not interchangeable. SDS systems give significantly faster drilling in concrete.
Q: How long do masonry drills last?
Varies enormously by concrete hardness and drill quality. Quality carbide-tipped masonry drill: 50-200 holes in standard concrete (light commercial concrete strength). Hard aggregate concrete or heavily reinforced concrete: shorter life — sometimes 20-50 holes per bit. SDS-plus bits in proper rotary hammer: dramatically longer life than standard chuck bits in standard drill (better impact energy + cooler operation). Replace when the carbide tip is worn, chipped, or when drilling significantly slower.
