Draper Storm Force® 230V SDS+ Rotary Hammer Drill, 900W

Drill and chisel through masonry, concrete, brick, and block with confidence using the Draper Storm Force® PT900SDSSF 900W SDS+ Rotary Hammer Drill — a capable, well-equipped 3-function hammer drill from Draper's Storm Force range that delivers strong drilling performance, a practical 4J of impact energy, and a comprehensive accessory kit at an accessible price point. Suited to tradespeople, site workers, and capable DIY enthusiasts who need a reliable, versatile SDS Plus drill for everyday construction and renovation drilling and chiselling tasks, the PT900SDSSF combines solid performance with the dependable build quality the Storm Force range is known for.

Running at up to 850rpm with an impact rate of 4,100 beats per minute and 4J of impact energy, the PT900SDSSF delivers productive, efficient drilling through masonry and concrete up to 26mm diameter — covering the anchor bolt holes, service penetrations, and fixing installations commonly encountered across building, electrical, plumbing, and renovation trades. The SDS Plus chuck provides secure, locking bit retention that handles the sustained rotary impact loads of hammer drilling with far greater efficiency and bit security than standard percussion drill chucks, while reducing vibration transmission to the operator during extended drilling sessions.

Three selectable functions cover the full range of everyday drilling and chiselling applications. Hammer drill mode combines rotation and impact for fast progress through masonry, block, and concrete. Standard rotary drill mode handles wood, metal, plastic, and other non-masonry materials without impact. Chisel mode disengages rotation entirely for pure impact chiselling — ideal for light breaking, tile and render removal, and surface preparation work. A safety clutch provides essential protection against the rotational kickback that occurs when a bit jams in hard material, disengaging the drive before injury can result — a critical safety feature on any hammer drill used for large-diameter masonry work.

A depth rod enables drilling to precise, consistent depths for anchor bolt installation and through-fixing work, while the adjustable side handle can be repositioned to suit the working angle and provide secure two-handed control. Two SDS Plus chisels — flat and pointed — and three SDS Plus drill bits are supplied along with the adjustable side handle, depth rod, and 2.2m cable with BS plug, all contained in a carry case for organised, protected storage and transport. At just 3.36kg the PT900SDSSF is notably lightweight, reducing fatigue during extended overhead or awkward-angle drilling work on site.

Specifications

FAQ Section

What are the three functions on the PT900SDSSF?
The PT900SDSSF offers three selectable operating modes: rotary drill for wood, metal, and plastic; hammer drill combining rotation and impact for masonry, brick, block, and concrete; and chisel mode delivering pure impact without rotation for light breaking, tile removal, and surface chiselling.

How does the PT900SDSSF differ from the SDSHD1050D?
The PT900SDSSF is a 900W 3-function Storm Force range drill offering 4J of impact energy at 4,100bpm. The SDSHD1050D is a 1,050W 4-function drill delivering 3.0J at 5,000bpm and adds a chisel lock mode not found on the PT900SDSSF. The PT900SDSSF's higher 4J impact energy makes it more capable for sustained chiselling tasks, while the SDSHD1050D's higher impact rate and chisel lock function suit precise directional chiselling and faster impact drilling. The Storm Force PT900SDSSF is the more accessible price-point option; the SDSHD1050D is suited to those requiring the additional chisel lock function and higher impact rate.

What is the safety clutch on the PT900SDSSF?
The safety clutch automatically disengages the rotary drive when the drill bit jams in hard material during hammer drilling, preventing the sudden violent torque reaction that can twist the drill and injure the operator. It is an essential safety feature for large-diameter masonry drilling with SDS Plus tools at this power level.

What accessories are supplied with the PT900SDSSF?
The PT900SDSSF is supplied in a carry case with two SDS Plus chisels (flat and pointed), three SDS Plus drill bits, an adjustable side handle, a depth rod, and a 2.2m cable with BS plug — a comprehensive kit covering the most common drilling and chiselling requirements immediately from the box.

Is the PT900SDSSF suitable for anchor bolt installation?
Yes. The 26mm masonry drilling capacity, depth rod for precise hole depths, and hammer drill function make the PT900SDSSF well suited to drilling anchor bolt and chemical anchor holes in concrete, block, and brick to the exact depths specified by fixings manufacturers.

What does 4J of impact energy mean for drilling performance?
Impact energy — measured in joules — indicates the force delivered with each hammer blow during hammer drilling. At 4J, the PT900SDSSF delivers more impact energy per blow than many comparable SDS Plus drills in its wattage class, making it more efficient at penetrating harder masonry substrates and producing cleaner, faster holes in concrete and dense block with less operator pressure required.

Is the PT900SDSSF suitable for professional site use?
Yes. The Storm Force range is designed for dependable performance in professional and trade environments. The PT900SDSSF's 900W motor, SDS Plus chuck, safety clutch, and comprehensive accessory kit make it a capable everyday tool for builders, electricians, plumbers, and general contractors across a wide range of drilling and chiselling applications.
