Tryton corded hammer drill TDW850 (model YTDW03KZ) – 850 W power, key chuck 10 mm

Tryton TDW850 corded hammer drill (model YTDW03KZ) is a compact, mains-powered tool intended for drilling and light chiselling in masonry, concrete and wood. With an input power of 850 W and a keyed 10 mm chuck, the drill combines percussion action and rotary modes to handle common repair, construction and installation tasks. Forward and reverse rotation enable screwdriving and backing out fasteners, while the compact housing and pistol grip support controlled operation in confined spaces.

Advantages

The 850 W motor delivers steady torque for drilling into brick, block and timber while the hammer function provides percussive energy for masonry work. A keyed 10 mm chuck ensures secure clamping of standard drill bits and accessories. Forward/reverse control increases versatility for both drilling and light screwdriving jobs. The corded design provides continuous power for longer tasks without battery limitations, and the compact form factor improves manoeuvrability in tight locations.

Suitable for

• Drilling holes in masonry, concrete and brick for anchors and fixtures
• Wood and metal drilling for basic installation and joining tasks
• Light chiselling or percussive work such as removing small amounts of mortar
• Screwdriving and fastening where forward/reverse control is required
• Home repairs, renovation and small construction projects

How to use

Select the appropriate drill bit and tighten it securely in the keyed 10 mm chuck using the chuck key. Choose the operating mode according to the material: use hammer mode for masonry and concrete, and rotary mode for wood and metal. Set the rotation direction to forward for drilling and screw insertion, and to reverse to remove bits or back out fasteners. Start drilling at low speed to establish position, then apply steady pressure and increase speed as needed. Maintain firm, two-handed control where possible and disconnect from the mains before changing bits or performing maintenance.

Usage recommendations

Wear appropriate personal protective equipment such as eye protection and hearing protection when using the hammer drill. For masonry work, use carbide-tipped masonry bits sized for the intended anchors or fasteners. Avoid excessive lateral force on the bit to reduce wear and risk of breakage. For prolonged operation, allow the motor to cool periodically and use clamps or supports to stabilise workpieces when drilling small or thin materials.
