The device described in the manual is the TITAN TTG953MLT 12V Cordless Rotary Tool. It is designed for grinding, cutting, sanding, polishing, and wire brushing of wood, plastic, and metal, particularly suited for working on hard-to-reach areas. The tool is intended for dry use only, meaning it should not be operated with water or other liquid coolants.
Function Description
The TTG953MLT is a versatile rotary tool that performs various tasks through interchangeable accessories. Its core function involves rotating accessories at high speeds to achieve different material removal or finishing operations.
Key functions include:
- Grinding: Using abrasive wheels for sharpening, deburring, smoothing, and removing rust from metal castings, lawnmower blades, screwdriver tips, knives, scissors, chisels, and other cutting tools. Silicon carbide grinding wheels are used for non-ferrous metal, rock, ceramic, and porcelain.
- Sanding: Utilizing sanding drums and sanding bands for working on wood, metal, and ceramic.
- Cutting: Employing cut-off wheels for abrasive cutting-off operations.
- Polishing: Using felt wheels with polishing paste for polishing precious metals like gold and silver, and radial nylon brushes for cleaning and polishing silver and jewelry. Steel wire brushes are also used for polishing metals and removing rust or corrosion.
- Carving/Engraving: Using engraving cutters for intricate work on ceramics (greenware), wood carvings, jewelry, scrimshaw, and printed circuit boards. HSS cutters are used for carving, cutting, and slotting in wood and plastics.
- Wire Brushing: Using steel wire brushes for rust and corrosion removal, and radial nylon brushes for cleaning and polishing.
The tool features a speed adjuster (1) to control the rotation speed, allowing users to select the appropriate speed for different materials and tasks. An on/off switch (8) controls the tool's power. Battery indicator lights (2) display the remaining battery capacity, and a work light (17) illuminates the work area. A shaft lock button (7) and tensioning nut (5) facilitate the secure attachment and removal of accessories.

Usage Features
Accessory Installation and Removal:
- To install or remove a collet (9), the shaft lock button (7) must be pressed down while rotating the tensioning nut (5). The spanner (13) is used to loosen or tighten the tensioning nut.
- Accessories are inserted into the collet (9) and secured by tightening the tensioning nut (5) with the spanner (13) while holding the shaft lock button (7) down.
- Important: Accessories should not be mounted more than 10mm from the tensioning nut to prevent vibration or spindle breakage. The maximum accessory diameter is 25mm.
Battery Pack Management:
- Release/Attach: The battery pack (4) is released by pressing two battery release buttons (3) and sliding it off the handle (15). To attach, align and slide it into the handle until it clicks.
- Charging: The battery pack (4) is charged using the supplied charger (10). The charger has green (11) and red (12) indicator lights to show charging status (ON for charging, OFF for fully charged or high battery temperature). Charging takes approximately 1 hour.
- Battery indicator lights (2): Three LEDs indicate battery capacity:
- 3 LEDs lit: >70%
- 2 LEDs lit: 35%-70%
- 1 LED lit: <35%
- Charging conditions: Charge and store the battery pack between 18-24°C (65-75°F) for optimal life and performance. Do not charge or store below 0°C (32°F) or above 45°C (113°F).
- Storage: For long-term storage, charge the battery to 30-50% capacity and boost charge once per year to prevent over-discharge.
Operation:
- Switching On/Off: Slide the On/Off switch (8) to "I(ON)" to start and "O(OFF)" to stop the tool.
- Speed Control: The speed adjuster dial (1) allows selection of rotation speeds from "1" (approx. 5000rpm) to "6" (approx. 25000rpm). The manual provides a table with recommended speed settings for different materials (e.g., 1-3 for plastics, 4-5 for stone/ceramics, 5 for soft wood/metal, 6 for hardwood/steel).
- Working Practices:
- Apply light pressure to the tool to avoid poor finish and motor overloading.
- Avoid bouncing and snagging accessories, especially in corners or sharp edges, to prevent loss of control and kickback.
- Never switch on the tool when it is in contact with the workpiece.
- Always hold the tool firmly during start-up to resist reaction torque.
- Use clamps to support workpieces whenever practical.
- Do not lay the tool down until the accessory has come to a complete stop.
- Ensure collet nut, chuck, or other adjustment devices are securely tightened after changing bits or making adjustments.
- Do not run the tool while carrying it at your side.
- When using rotary files, cut-off wheels, high-speed cutters, or tungsten carbide cutters, ensure the work is securely clamped.
- For side grinding, use the grinding accessory at a 30-40° angle.
- For peripheral grinding (cutting), use the cutting accessory at a 90° angle. Side forces applied to cutting accessories may cause them to shatter.
- Always wear appropriate personal protective equipment, including eye protection (face shield, safety goggles/glasses), dust mask, hearing protectors, gloves, and a workshop apron.
