PRIMARY USES
1. Heavy-Duty Concrete and Masonry Drilling for Equipment Installation
Primary Use: A powerful electric rotary hammer (800W) with a 26mm drilling capacity in concrete, designed for heavy-duty drilling into concrete, masonry, brick, and stone to install anchors, fixtures, shelving, handrails, and medical equipment securely in healthcare facilities .
How it helps: For the biomedical engineer, maintenance technician, and facilities manager, the SDS-plus chuck system ensures quick, tool-free bit changes and efficient power transfer, making it far faster and more effective than standard hammer drills . The 26mm capacity allows drilling for M20 or M22 anchor bolts used in heavy equipment installation and structural anchoring. The 800W motor delivers sufficient impact energy (approximately 2.3-3.0 Joules) for efficient drilling in reinforced concrete . For the healthcare facility, this means reliable, secure installation of essential medical equipment and infrastructure without compromising structural integrity.
2. Chiseling and Light Demolition for Renovation and Maintenance
Primary Use: With the rotation stop function, the rotary hammer operates as a demolition hammer for chiseling tasks such as removing tiles, breaking up small concrete sections, chasing channels for conduit and piping, and removing old mortar during renovation projects .
How it helps: For the maintenance team, the chiseling function allows for efficient removal of damaged flooring, wall finishes, and fixtures during renovation without requiring a separate demolition tool. This is particularly valuable in healthcare settings where renovation work must be completed quickly to minimise disruption to patient care areas. The SDS-plus system accepts a wide range of chisel bits for different applications .
3. Installing Conduit, Piping, and Cable Trays in Healthcare Facilities
Primary Use: Used for drilling precise holes in concrete and masonry for running electrical conduit, plumbing pipes, data cables, and medical gas lines during new construction, expansion, or renovation projects .
How it helps: For the facilities manager and project coordinator, the rotary hammer’s 26mm capacity is ideal for drilling holes for standard conduit sizes used in healthcare electrical and plumbing installations. The depth stop ensures consistent drilling depths for accurate installation . The anti-vibration design and ergonomic grip (typically with a soft rubberised handle) reduce user fatigue during extended use .

SECONDARY USES
1. Drilling in Wood and Steel: When fitted with the appropriate SDS-plus to standard chuck adapter, the tool can be used for drilling into wood (up to 30mm) and steel (up to 13mm) for general maintenance and fabrication tasks .
2. Anchor and Fixture Installation: Used for installing expansion anchors, drop-in anchors, and chemical anchors in concrete for securing shelving, equipment, and structural fixtures .
3. Demolition of Non-Load-Bearing Structures: Suitable for light demolition of non-load-bearing walls, removal of old tiles, and breaking up small concrete sections during refurbishment projects .
4. Grooving and Channelling: Used for creating channels in masonry for running electrical cables and plumbing pipes during installation .
