Classification by shank standard and application

Concrete drill bit sets are classified primarily by shank standard and compatible drill type. SDS-Plus shanks are for hammer drills, allowing quick tool-free installation and removal and efficient impact force transmission. Round cylindrical shanks are used with standard handheld drills, clamped tight by three-jaw chucks. Each shank standard suits a distinct application group.

SDS-Plus shank drill bit sets such as 072B, 1003A and 1004A specialize in drilling reinforced concrete and hard materials.

Set 1003A has 160mm working length, meeting the need for deep drilling on thick concrete structures. Set 1004A comprises 5 bits Ø5-10mm, suitable for electrical, plumbing and light mechanical installation work.

Cylindrical shank drill bit sets such as 201C, 211C, 299B, 250C and 251C are used with handheld drills. Set 201C comprises 5 bits Ø4-10mm, equipped with semi-positive carbide tips and double flutes. Set 211C has 5 bits Ø4-10mm, drilling on concrete, stone, solid brick, hollow brick and plasterboard. Set 299B comprises 8 bits Ø3-10mm, meeting diverse needs from small to medium hole drilling. Set 250C has 8 pieces Ø3-10mm, while 251C comprises 5 pieces Ø4-10mm.

Size and number of bits in sets

Concrete drill bit sets have piece counts from 4 to 25 bits, meeting needs from small individual jobs to large-scale projects. 4-5 bit sets suit individual installers or maintenance work. 7-10 bit sets are for small construction teams or medium projects. 12-25 bit sets serve large construction teams or professional tool inventories.

4-bit sets such as 100C comprise Ø5, 6, 8, 10mm, length 160mm. 5-bit sets such as 201C, 211C, 251C, 1004A, 1005A, 112Q, 104B and 115C have diameter ranges from Ø4-12mm. 7-bit sets such as 105D and 1002A expand the size range to Ø20mm.

8-bit sets such as 299B and 250C have diameters Ø3-10mm, including small Ø3mm size for small screw holes. 10-bit sets such as 116D, 072B and 1003A have ranges Ø5-14mm or Ø6-14mm. 12-bit sets such as 157L and 25-bit sets such as 157M provide multiple sizes at the same diameter for large construction sites.

Materials and manufacturing technology

Concrete drill bit tips are made from tungsten carbide alloy, with high wear resistance when in contact with reinforced concrete and stone. 100% solid carbide as on 112Q delivers powerful breaking capability. Semi-positive carbide tips on 201C balance durability and penetration capability. Adaptive cutting edge design on the Rockfaster line optimizes performance for each diameter.

Single or double flutes guide chips out of the drill hole, reducing temperature and increasing drill bit life. Double flutes on 201C evacuate dust faster than single flutes. Semi-circular flutes on 115C and 104B support efficient dust extraction during deep drilling. Centering tip design helps start drill holes accurately, reducing slippage on hard surfaces.

3-cutting-edge technology on the Booster Plus line such as 115C and 104B increases concrete breaking and dust evacuation capability. 4-cutting-edge system on the 4G4 line such as 112Q enhances drilling speed on reinforced concrete. Cutting edge count varying by diameter on 1002A and 1005A optimizes performance for each size.

Applications on construction material types

Concrete drill bit sets drill on standard concrete, reinforced concrete, solid brick, hollow brick, natural stone, plasterboard and lightweight concrete blocks. Each material type requires appropriate drill bit diameter and length. Reinforced concrete needs drill bits with solid carbide tips and multiple cutting edges. Solid brick and natural stone require drill bits with fast chip-evacuating flutes.

Drilling reinforced concrete uses SDS-Plus shank sets such as 072B, 1003A, 1002A, 1005A, 104B and 115C. These sets have solid carbide tips and adaptive cutting edge systems, withstanding strong impact force from hammer drills.

Drilling standard concrete, solid brick, hollow brick and plasterboard uses cylindrical shank sets such as 201C, 211C, 299B, 250C and 251C. These sets suit handheld drills, high rotation speed and moderate pressure. Drilling natural stone and block walls uses the Twister Plus line such as 116D, 100C and 105D with optimized flute design.

Selecting drill bit sets by work requirements

Choose concrete drill bit sets based on drill type, construction material, hole size and frequency of use. Hammer drills need SDS-Plus shank sets, handheld drills need cylindrical shank sets. Electrical and plumbing installation work needs 4-5 bit sets Ø5-10mm. Concrete structure construction needs 7-10 bit sets Ø5-20mm. Professional tool inventories need 12-25 bit multi-size sets.

Individual installers choose 100C, 201C, 211C, 251C or 1004A with 4-5 bits Ø4-10mm. Small construction teams choose 105D, 299B, 250C or 1002A with 7-8 bits Ø3-20mm.

Large construction teams choose 116D, 072B, 1003A, 157L or 157M with 10-25 multi-size bits. Reinforced concrete construction sites choose the Rockfaster or Booster Plus line such as 1005A, 112Q, 104B and 115C with solid carbide tips.

When deep drilling on thick walls or concrete floors is needed, choose sets with 160mm working length such as 1003A, 100C and 105D. When small holes for screws are needed, choose sets with Ø3-4mm diameter such as 299B and 250C. When large holes for anchor bolts are needed, choose sets with Ø12-20mm diameter such as 1002A.
