1. Universal spindle compatibility (Type 100): Designed for grinders in the 100/200 series, supports 45 mm spindles with +/- 0.2 mm tolerance. Compatible with 95% of mainstream models. Dual-lock collet design enables tool changes for discs from 1.3 cm to 7.6 cm in diameter. 2. Universal spindle compatibility (Type 100): Fits Makita 100/200 series grinders (45 mm spindles, +/- 0.2 mm tolerance) and 95% of common models. Dual-lock collet allows tool changes for discs from 1.3 cm to 7.6 cm in diameter. 3. Versatile use (68 kg maximum load): Suitable for tile work in residential settings and commercial floor installations. Supports discs from 10.2 cm to 30.5 cm and is compatible with wet/dry grinders. Features heat-dissipating clamps to prevent thermal drift during longer 4-hour cycles. 4. 45-degree chamfer precision grinding stand: Robust steel frame with deformation-resistant design and corrosion-resistant alloy construction for stability in tile work. Ergonomic positioning minimizes vibration to deliver clean, repeatable bevel cuts. Use scenarios: - Residential tile installation or renovation (bathroom/kitchen) where precise 45-degree chamfer edges are required for clean, uniform tile joints. - Commercial floor tiling projects that demand long, continuous operation; the heavy-duty 68 kg capacity and heat-dissipation clamps help maintain accuracy over extended cycles. - Projects involving multiple tile sizes that require quick tool changes between discs (1.3 cm to 7.6 cm) using the dual-lock collet for efficient workflow.
