TECHPLUS Drill Bit Sharpener Guide Jig (3 Pack)
The TECHPLUS kit offers three sharpening guides with angles at 90°, 118°, and 135°. Built as a manual tool, it helps maintain precise and repeatable edge geometry across a variety of drill bit styles. By aligning the bit with fixed angle grooves, users can reproduce consistent results with reduced guesswork. The set is ideal for restoring dull bits and extending tool life. Its lightweight construction supports frequent handling in a busy workshop.
AGLOO Drill Bit Sharpening Guide Jig (Set of 3)
The AGLOO set features 90°, 118°, and 135° angle options, designed for manual operation without power. It emphasizes a reliable, portable solution for makers and machinists who need precise angles on demand. The design employs engineering-grade polymer for durability, resisting wear in regular bench grinder use. This trio offers flexibility for different bit types and applications while preserving edge accuracy across sharpening sessions.
General Tools Drill Grinding Attachment #825
General Tools’ attachment is designed to extend drill bit life by re-honing and sharpening bits to factory-like accuracy. Its pivoting neck allows equal sharpening on both sides of the bit, and the tool supports a range of point angles to accommodate many bit styles and countersinks. A non-marking depth stop protects surface finish, while a vice clamp provides quick, stable mounting. This tool is well-suited for users seeking a versatile, stable sharpening solution for everyday bits.
Drill Doctor DD350X Drill Bit Sharpener
The DD350X is an electric sharpener designed for quick, consistent results. It sharpens bits from 3/32″ to 1/2″ and emphasizes a 118° sharpening angle. The device uses a dedicated V-block to secure the bit and streamline the sharpening process, reducing alignment errors. Constructed for durability, it includes a six-foot power cord to reach a standard workbench. It is best for users who prefer an automated, two-step sharpening workflow with minimal manual adjustment.
Generic 118° & 135° Drill Bit Sharpening Jig
This sharpening jig focuses on 118° and 135° restoration with a foolproof alignment system. Its mechanical simplicity—position-hold-grind—delivers repeatable results without electronics. The high-density, heat-resistant polymer construction resists wear over many sharpening cycles, maintaining tolerances and delivering factory-like edges for dull bits that still have usable life left. A reliable option for busy workshops that value consistency and durability.
Generic 118° & 135° Drill Bit Sharpener (2pcs 135°)
This two-pack provides 118° and 135° precision with a foolproof alignment system. It emphasizes mechanical simplicity and reliability, enabling a three-step process: position, hold, grind. The durable polymer construction is designed to withstand extensive workshop use, keeping tolerances stable across thousands of sharpening cycles. It’s a practical choice for hobbyists and professionals who need dependable, repeatable results without electronic components.
Generic 118° & 135° Drill Bit Sharpener (2pcs 118°,135°)
This pair covers both 118° and 135° restoration with a consistent alignment system. Its design emphasizes mechanical reliability over electronics, making it suitable for shop workers who value straightforward operation. The polymer construction helps resist warping and degradation, while the three-step process promotes repeatable results across different bit sizes and materials.
Buying Guide
- Angle range: Decide which angles you need most. Most kits offer 90°, 118°, and 135°, while others include additional presets like 88°, 68°, or 41°. If you work with a variety of bits, a multi-angle jig minimizes swaps.
- Power vs manual: Manual jigs are affordable and portable, suitable for occasional sharpening. Electric sharpeners provide speed and consistency for high-volume use, but require electricity and careful maintenance.
- Material and durability: Look for high-density polymer or metal components that resist wear. Jigs with heat-resistant parts maintain tolerances through thousands of sharpening cycles.
- Ease of use: Foolproof alignment systems, clear angle guides, and secure mounting help ensure repeatable results. A stable depth stop or vice clamp reduces slip during sharpening.
- Bit compatibility: Confirm the jig accommodates the common drill sizes you use (e.g., 3/32″ to 1/2″ or larger). Some tools also adjust for countersinks or specific point geometries.
- Maintenance: Consider how easy it is to clean and replace worn grinding surfaces, especially for diamond or carbide wheels in electric models.
- Safety: Use clamps and guards to protect fingers and surfaces. Non-marking stops and protective housings reduce the risk of scarring workpieces.
Overall, manual jigs provide reliable, cost-effective sharpening with repeatable angles, while electric sharpeners offer speed and convenience for frequent use. When selecting a kit, consider your typical bit sizes, preferred angles, and whether you value portability or throughput in a workshop setting.
