For drilling into concrete, brick or masonry, a rotary hammer (SDS-plus) drill is the right tool — it combines rotation with a hammering action that breaks the material as it bores. Multi Trade Combines recommends the Bosch GBH 2-26 RE as the benchmark choice for contractors and site teams in Guwahati and across Northeast India.
A standard corded or cordless drill can accept masonry bits, but its rotation-only action makes drilling into concrete slow and punishing on the machine. A rotary hammer adds an electro-pneumatic hammering mechanism — the bit strikes the surface thousands of times per minute while rotating — cutting drilling time in concrete by 3–5× versus a standard drill.
For light masonry (brick, block, plaster) a corded impact drill with a good masonry bit can work, but for RCC columns, beams, slabs or hard stone, an SDS-plus rotary hammer is essential. The Bosch GBH 2-26 RE handles up to 26 mm in concrete with its 800 W motor and 2.7 J impact energy — the most popular contractor rotary hammer we stock.
Impact energy (Joules): Higher joules means faster drilling in harder material. The GBH 2-26 RE at 2.7 J suits 6–26 mm holes in RCC; for bigger demolition or anchor holes above 28 mm, step up to a 5–8 J SDS-max hammer.
SDS-plus vs SDS-max: SDS-plus is the standard for drills up to 26 mm — bits are widely available. SDS-max suits heavy-duty drills above 26 mm. Most site teams in Assam use SDS-plus; SDS-max is for specialist chiselling or large anchor bores.
Three modes: Look for a machine with rotation-only, hammer-only (chiselling) and rotary hammer modes — the GBH 2-26 RE has all three, making it usable for drilling, chiselling mortar and setting anchors.

A Bosch GSB impact drill (standard impact driver) works for light brick and block, but its impact energy (measured in kg·cm, not Joules) is much lower than an SDS rotary hammer. For RCC or dense concrete, the GBH 2-26 RE rotary hammer is the correct tool.
