Genuine Bosch 450 W impact drill with 13 mm keyed chuck — reliable hammer-drill performance in brick, block, wood, and metal.
The Bosch GSB 450 is a 450 W impact (hammer) drill from Bosch's Blue professional power tool range, fitted with a 13 mm keyed chuck. It combines standard rotary drilling (for wood and metal) with a hammer-drill function that delivers rapid impacts in addition to rotation, enabling effective drilling into brick, concrete block, and stone surfaces. At 450 W, it covers the most common drilling tasks on a construction site or in a workshop: anchor holes in brick walls for shelf brackets and equipment mounting, clearance holes in steel plate, pilot holes in timber, and general maintenance drilling.
Multi Trade Combines is an authorised Bosch dealer on AT Road, Guwahati. The Bosch GSB 450 is one of the most commonly sold entry-level professional drills in Northeast India — contractors, site supervisors, maintenance staff, and small workshops rely on it for its simplicity, Bosch motor quality, and the wide availability of 13 mm keyed accessories. It is lighter than variable-speed models, which is an advantage for overhead drilling in ceiling panels and high wall anchoring.
Civil contractors and MEP subcontractors on building sites across Assam use the GSB 450 for drilling anchor holes in brick and block walls for conduit clamps, pipe supports, equipment mounting brackets, and facade fixings. The Guwahati construction market — apartment blocks, commercial fit-outs, government buildings — creates steady demand for this workhorse tool.
Maintenance engineers in tea factories, oil field facilities, and small industrial units use it for routine maintenance drilling — fitting name plates, mounting electrical panels, bolting cable trays, and securing machine guards. It is also popular with individual contractors and sole traders who need a reliable, low-cost professional drill for fitting door frames, window bars, and iron grills — a common task in Assam's residential market.
The GSB 450 pairs with Bosch SDS-plus rotary hammers for heavy concrete drilling, with Bosch angle grinders for cutting and grinding, and with TAPARIA or Bosch screwdriver bits when driving screws without a dedicated screwdriver. Complete power tool packages from our Bosch range at Multi Trade Combines cover all site drilling needs.

The Bosch GSB 450 is a 450 W impact drill with a 13 mm keyed chuck designed for light-to-medium drilling in masonry, wood, and metal. The GSB 600 RE is a 600 W variable-speed version with electronic speed control, offering more versatility for mixing, driving, and varied drilling tasks. The GSB 450 is the right choice for users who primarily drill holes in brick and concrete walls for plugs and anchors — fixed speed, simple operation, maximum reliability on that specific task. For professionals who need variable speed and a wider range of attachments, the GSB 600 RE is more versatile.
The GSB 450's impact drill function is designed for brick and natural stone. For reinforced concrete — columns, slabs, lintels — the impact frequency of a hammer drill may not be sufficient for productive drilling, and hitting rebar causes immediate bit damage. For consistent drilling in RCC structures, an SDS-plus rotary hammer (Bosch GBH range) with hammer-only mode is the correct tool. For occasional anchor holes in a concrete wall (not structural RCC), the GSB 450 with a quality carbide-tip masonry bit will complete the task, just more slowly than an SDS hammer drill.
