CELMA UDR.2-B PRCz-13GEO 950W 13mm iskuporakone

On a busy construction site, a contractor needs to bore through concrete, steel, and wood without switching tools. The CELMA UDR.2-B PRCz-13GEO impact drill delivers that versatility with a 950W motor and two-speed gearbox, handling everything from light screwdriving to heavy masonry drilling. Its keyed 13mm chuck grips bits firmly, while the variable speed trigger and reversible rotation give precise control for any task.

Key specifications

• Power input: 950 W
• Chuck type: Keyed chuck, capacity 1.5–13 mm
• Two-speed gearbox: 0–1100 rpm and 0–2800 rpm no-load speeds
• Impact rates: 0–17,600 bpm (gear 1) and 0–44,800 bpm (gear 2)
• Max drilling diameters: 13 mm in steel, 30 mm in wood, 16 mm in concrete
• Spindle thread: 1/2" - 20 UNF
• Cable length: 2.5 m, 230V ~50Hz

Why choose it

The drill's hammer function engages only when needed, so you can switch from rotary-only drilling in wood or metal to impact drilling in masonry without changing tools. The two-speed gearbox optimizes torque and speed for different materials: low gear for high-torque screwdriving and large holes, high gear for fast drilling in soft materials. The keyed chuck provides maximum bit grip, preventing slippage even under heavy loads.

Ideal use cases

• Drilling anchor holes in concrete and brick walls
• Boring large holes in timber framing and plywood
• Driving screws and bolts with the reversible function
• Metal fabrication and automotive repair work
• General construction, renovation, and DIY projects

Good to know

The 2.5m power cord offers ample reach, and the ergonomic handle with soft grip reduces fatigue during extended use. The drill's compact design allows access to tight spaces, while the side handle (included) provides extra stability for high-torque applications. Always wear appropriate safety gear, and use the depth stop for consistent hole depths.
