The MR-20G version expands the range to 3–20 mm and provides 95°–135° point angle adjustment, with 18 collets for broader bit compatibility. It supports two grinding wheel types (CBN and SDC), enabling adaptation to various material hardness. This model focuses on versatility and precision for mid-to-large diameter bits, making it suitable for heavier-duty applications and professional workshop environments where larger bits are frequently sharpened.

Buying Guide: Key Purchase Considerations

• Bit range and compatibility: Match the sharpener to the common drill sizes you use. Some units cover up to 1/2″ or 15 mm, while others extend to 20 mm. Consider future needs and whether upgrades or additional chuck options are available.
• Angle adjustment: Look for adjustable point angles, typically between 95° and 135°, and the ability to set consistent angles across multiple bits. This affects drilling accuracy and edge durability in various materials.
• Wheel type and durability: Diamond or carbide wheels offer different longevity and heat management. Diamond wheels are durable for metal and masonry bits, while CBN wheels can enhance high-speed steel performance. Compare heat buildup and cooling design if you work with hotter materials.
• Bit-tip support: Some sharpeners feature split-tip cutting or lip relief adjustments to improve chip evacuation and reduce wear. Consider whether you need split-tip capability for extended life.
• Build quality: All-metal housings and robust chucks provide stability and reduce deformation during sharpening. A solid base and alignment features help maintain repeatable results over time.
• Portability vs. capacity: Portable units are ideal for fieldwork, but larger, multi-gantry sharpeners may handle more bits at once. Choose based on workspace size and workflow.
• Ease of setup: Look for models with straightforward alignment, two-step sharpening where applicable, and clear instructions. Simpler setups can save time in busy shops.
• Safety features: Consider guards, stable bases, and safe handling of grinding wheels. A secure bit clamping system minimizes slips during sharpening.
