Concrete drill bit

The concrete drill bit product group serves hole-making on concrete substrates, brick walls, natural stone and asphalt in construction, electrical and plumbing installation, and equipment bracket anchoring.

The range includes diamond tile drill bits Ø5-14 mm for rotary drilling without percussion to avoid cracking ceramic surfaces, carbide masonry bits with SDS-plus shank Ø8-20 mm for hammer drills, and UDKB series diamond core bits Ø32-300 mm with 420 mm depth for large holes through thick walls. Diamond tile bits penetrate ceramic tile, fine porcelain, granite, and marble without surface cracking because they use pure rotation.

Carbide masonry bits drill holes for drive anchors or expansion anchors when securing drill stands to substrates. Core bits feature induction-brazed diamond segment cutting rings, UNC 1 1/4 internal thread compatible with Picus machines, and bit tubes that can be re-welded when worn. Vinatools distributes genuine REMS products imported from Germany with full manufacturer warranty coverage.

Diamond tile bits penetrate ceramic tile, fine porcelain, granite, and marble without surface cracking because they use pure rotation. Carbide masonry bits Ø8, Ø15, Ø20 mm with SDS-plus shank drill holes for drive anchors or expansion anchors when securing drill stands to substrates. UDKB series core bits feature induction-brazed diamond segment cutting rings, UNC 1 1/4 internal thread compatible with Picus machines, and bit tubes that can be re-welded when worn.

Combo sets containing 3-4 core bit sizes purchased as complete sets cost less than buying individual sizes, suitable for construction teams needing multiple diameters. Selecting the correct bit type according to substrate material and required hole diameter increases bit life and reduces drilling time.

Classification by drilling function

The concrete drill bit group divides into three main types by function: diamond tile bits for rotary drilling, carbide masonry bits for percussion drilling, and diamond core bits for wet drilling. Each type meets specific technical requirements for substrate material, hole diameter and cooling method during drilling.

Diamond tile bits include sizes 181710 R Ø5 mm, 181711 R Ø6 mm, 181712 R Ø8 mm, 181713 R Ø10 mm, 181714 R Ø12 mm and 181715 R Ø14 mm. These bits feature bonded diamond particles, drill by rotation without percussion, so they penetrate ceramic tile, fine porcelain, granite, and marble without surface cracking. Internal wax core provides cooling during dry drilling, eliminating the need for continuous water supply.

Carbide masonry bits with SDS-plus shank include 079013 Ø8 mm for centering pin drilling, 079018 Ø15 mm for M12 drive anchors, and 079019 Ø20 mm for M12 expansion anchors. The Ø8 mm bit sits inside the G 1/2 centering pin to create a support point so the diamond ring of the core bit does not slip when starting the hole. The Ø15 mm bit drills holes sized precisely for M12 drive anchors; accurate holes allow anchors to develop full holding force and prevent drill stand base movement. The Ø20 mm bit drills holes for M12 expansion anchors in brick walls and masonry; correctly sized holes allow anchors to expand evenly and hold drill stands securely.

UDKB series diamond core bits

UDKB series diamond core bits serve drilling in reinforced concrete, masonry walls, natural stone and asphalt with diameters from Ø32 to Ø300 mm, drilling depth 420 mm. The cutting ring comprises multiple diamond segments induction-brazed with tin, UNC 1 1/4 internal thread self-tightens during operation, and the bit tube can be re-welded when worn.

Small sizes from Ø32 to Ø62 mm include 181010 R Ø32 mm with 4 segments, 181015 R Ø42 mm with 4 segments, 181020 R Ø52 mm with 5 segments, and 181025 R Ø62 mm with 6 segments. The beveled cutting ring provides smooth cutting rhythm, reducing vibration when drilling electrical and plumbing conduits through concrete slabs.

Medium sizes from Ø72 to Ø132 mm include 181030 R Ø72 mm with 7 segments, 181035 R Ø82 mm with 7 segments, 181040 R Ø92 mm with 8 segments, 181045 R Ø102 mm with 8 segments, 181050 R Ø112 mm with 9 segments, 181055 R Ø122 mm with 10 segments, 181057 R Ø125 mm, 181059 R Ø127 mm with 10 segments, and 181060 R Ø132 mm with 11 segments. Segment count increases with diameter to distribute cutting force evenly, reducing wear at each contact point.

Large sizes from Ø152 to Ø300 mm include 181065 R Ø152 mm with 12 segments, 181070 R Ø162 mm with 12 segments, 181075 R Ø182 mm with 12 segments, 181080 R Ø200 mm with 12 segments, 181085 R Ø225 mm with 13 segments, 181090 R Ø250 mm with 14 segments, and 181095 R Ø300 mm with 22 segments. The Ø300 mm size uses 22 segments to maintain stable cutting speed across the large circumference, preventing drill motor overload.

Core bit combo sets for cost savings

Diamond core bit combo sets contain 3-4 commonly used diameter sizes; purchasing complete sets costs less than buying individual sizes. These sets suit construction teams needing multiple hole diameters in the same project, reducing order lead time and individual shipping costs.

Set 181100 R contains 4 bits Ø62, Ø82, Ø102, Ø132 mm all with 420 mm drilling depth and UNC 1 1/4 internal thread. Set 181101 R contains 3 bits Ø62, Ø82, Ø132 mm, set 181102 R contains 3 bits Ø52, Ø112, Ø132 mm, and set 181103 R contains 3 bits Ø62, Ø102, Ø125 mm. All these sets use UNC 1 1/4 internal thread compatible with Picus machines, requiring no adapter when changing bit sizes.

UDKB LS series sets include 181111 R with 3 bits Ø62, Ø82, Ø132 mm, 181112 R with 3 bits Ø52, Ø112, Ø132 mm, and 181113 R with 3 bits Ø62, Ø102, Ø125 mm. The LS series has segment structure similar to standard UDKB series, same 420 mm drilling depth and UNC 1 1/4 internal thread. Set 181700 R contains diamond tile drill bits Ø6, Ø8, Ø10 mm and accessories, serving drilling in ceramic tile, stone, granite, marble without water cooling.

Selecting bits according to substrate material

Selecting concrete drill bits depends on substrate material, required hole diameter and cooling method during drilling. Ceramic tile, fine porcelain, granite, and marble require diamond bits with rotary drilling without percussion to avoid surface cracking. Concrete, brick walls, and masonry accept carbide bits with percussion drilling or diamond core bits with wet drilling.

Diamond tile bits Ø5-14 mm serve small holes in ceramic tile, fine porcelain, granite, and marble when installing screws, hanging hooks or small electrical conduits. Internal wax core provides cooling during dry drilling, eliminating the need for continuous water supply, suitable for construction in finished interior spaces. Carbide masonry bits Ø8-20 mm with SDS-plus shank serve anchor holes in concrete, brick walls, and masonry when installing brackets, slide rails or core drill stands. Hammer drills generate percussion force helping bits penetrate hard materials quickly.

Diamond core bits Ø32-300 mm serve large holes in reinforced concrete, masonry walls, natural stone, and asphalt when installing electrical and plumbing conduits, ventilation ducts or fiber optic cables. Wet drilling with water cools diamond segments, increasing bit life and reducing airborne dust during drilling. UNC 1 1/4 internal thread self-tightens during operation, requiring no auxiliary thread lock, reducing bit change time between shifts.

Operation and storage considerations

Operating concrete drill bits correctly extends bit life and reduces breakdown risk. Diamond tile bits use rotation only; do not activate percussion mode on the drill. Carbide masonry bits with SDS-plus shank require hammer drills with percussion mode, rotation speed lower than wood or metal bits. Diamond core bits require continuous water cooling, sufficient flow rate to prevent segment dry-burning.

Check UNC 1 1/4 internal thread before mounting core bits on machine spindle; worn or deformed threads cause bit looseness during rotation. Clean threads after each drilling shift; concrete dust deposited in threads makes bits difficult to remove. Store bits in sealed cases, avoid impact causing diamond segment breakage or bit body bending. Store diamond tile bits in dry locations; moisture-affected wax core reduces cooling effectiveness.

Selecting the correct bit type according to substrate material and required hole diameter increases drilling productivity, reduces equipment wear and ensures hole quality. Core bit combo sets provide cost savings for construction teams needing multiple diameter sizes in the same project.
