Clarke CBS20 Electric Sharpener
The Clarke CBS20 is a compact electric sharpener designed for DIY and light professional use. It handles 3 mm to 12 mm HSS drill bits, making it suitable for common metal and mild steel tasks. With a 230V supply and a 95W motor, it offers straightforward operation, suitable for small workshops and garages. The device focuses on preserving the original tip geometry, supporting quick re-sharpening to maintain accurate hole placement. Its user-friendly design reduces the risk of overheating during sharpening, a common issue when using blunt bits on metalwork. For hobbyists upgrading from manual stone sharpening, this unit provides reliable, consistent results with minimal setup.
Key considerations include the availability of spare grinding stones and whether you need a dedicated drill bit guide. Its compatibility with standard 3–12 mm HSS bits covers most common household and basic construction tasks. If you frequently work with steel fasteners, maintaining sharpness is critical to avoid wandering or bit snatching. The Clarke CBS20 delivers a straightforward, plug-and-play experience for those who prioritise ease of use and predictable performance in a compact package.
Sealey Sms2008 Bench Sharpener
The Sealey Sms2008 is a bench-mounted drill bit sharpener offering quick, dependable sharpening for 3–13 mm bits. With an 80W motor, it suits busy workshops where frequent re-sharpening is required. It supports HSS, Titanium, Cobalt, and Carbon Steel bits, helping maintain cutting efficiency across varied applications. The quick-angle setup ensures consistent tip geometry, making drilling smoother and more predictable. The compact bench-mount design helps save space while providing stability during grinding and re-shaping tasks.
Users should evaluate mounting options and the availability of replacement grinding stones. For those who prioritise speed and repeatable results, the Sms2008’s straightforward operation is a strong match. Its compatibility with a broad range of drill bit materials means it’s a versatile choice for general fabrication, home renovations, and light professional work where reliable sharpness matters most.
Best Price Square CBS43 Sharpening
The Clarke CL CBS43 is a robust sharpener designed to fit to drills with a 43 mm collar and a 1/2″ drill chuck. It comes with a replacement grinding stone and a built-in drill bit guide to ensure the correct sharpening angle. This makes it a practical choice for users who want predictable outcomes without complex setup. The 43 mm collar compatibility broadens the range of compatible machines, which can simplify integration into existing workshop setups. For shops dealing with a mix of A–grade HSS bits and common carbide-tipped tools, the CBS43 provides a dependable sharpening solution in a compact form factor.
Consider whether your drill press or handheld drill offers the appropriate mounting interface. The built-in guide reduces user error, which helps maintain consistent hole quality. If you frequently rework older bits or need a quick refresh, the CBS43 can deliver steady results with minimal fuss and downtime.
Draper 98518 Sharpener
The Draper 98518 Sharpener is a 230V, 80W bench unit designed to sharpen 3–13 mm drill bits. It sharpens points to a 118° angle, suitable for typical HSS, titanium, cobalt, carbon steel, and split-point bits. This configuration aims to restore efficient drilling performance while supporting a range of common bit types used in metalworking and woodworking projects. The 118° angle is a conventional target for balanced cutting efficiency and control, enabling consistent entry into material without excessive wandering.
For users working with mixed bit families, the Draper option provides a versatile, stable platform. When selecting a sharpener, consider whether you require a fixed point angle or adjustable options for specialty bits. Draper’s approach prioritises reliable results with a straightforward workflow, making it suitable for ongoing maintenance in home workshops and small fabrication shops.
MULTI-SHARP 2001 Universal
The MULTI-SHARP 2001 Universal Sharpener is designed for 3–13 mm bits and covers a broad range of cutting tools including HSS, masonry, SDS-plus, centre-point, brad-point, and flat wood bits. It also sharpens small tools such as scribers, bradawls, punches, cold chisels, and screwdrivers, extending a wide array of tool life in a single device. The kit focuses on restoring accurate tip shapes and relief angles, which helps maintain cutting performance and reduce bit wear. With compatibility across multiple bit types, it serves workshops that handle diverse projects, from metal fabrication to woodworking and precision tasks.
Consider the complexity of the bits you routinely sharpen. For mixed tasks, this universal approach can reduce the need for multiple dedicated sharpeners. The inclusion of 3–13 mm bits aligns well with common workshop inventories, offering a practical balance of scope and affordability for home garages and small studios.
Buying Guide
- Bit range and compatibility: Confirm the sharpener supports the diameters and material types you use most (HSS, TiN, cobalt, carbide, etc.). If you work with a variety of bits, consider models offering broader ranges, such as 3–13 mm or 3–20 mm, and note any special bits (SDS, brad-point, split-point).
- Mounting style: Bench, wall, or portable units affect workspace layout. Bench-mounted units are common in hobbyist workshops, while portable units suit mobile setups or tighter spaces. Consider existing drill stands and compatibility with your drill press.
- Angle accuracy and relief: A precise sharpening angle and lip relief directly influence drilling performance. Look for configurable angles (e.g., 95°–135°) or fixed angles that match your typical materials and bit types.
- Grinding wheel type: Some models use standard stones; others employ advanced wheels like cubic boron nitride (CBN) for improved wear resistance and smoother finishes. A premium wheel can extend tool life but may require careful maintenance.
- Ease of use and safety: Features such as built-in guides, clear indicators, and stable mounting enhance safety and repeatable results. For beginners, a model with guided sharpening reduces the learning curve.
- Replacement parts and consumables: Check availability of replacement stones and collets. Accessible parts help maintain performance over time and reduce downtime.
- Material coverage: If you encounter masonry or carbide tools, verify that the sharpener supports those materials or provides appropriate adaptors.
- Maintenance and warranty: A reliable warranty and accessible customer support are valuable for longer-term use and resale value.
In choosing the right sharpener, balance your workload, space, and the variety of bits you sharpen. For a compact home workshop, a bench-mounted model with a clear guide and 3–13 mm range may be ideal. For professional use with frequent re-sharpening of varied tools, models offering broader ranges, robust wheels, and precise angle control provide the best long-term value. Always inspect safety features and ensure compatibility with your drill and work environment. This way, you preserve cutting efficiency, reduce heat buildup, and extend the life of essential drill bits.
