Best for layout and measurement tasks needing an integrated protractor and center finder. The MachEl tool combines protractor accuracy with a square rule and divider functionality, making it suitable for precise drilling setups and angle checks around 135° when paired with a suitable bit or gauge.
Caution: Not a dedicated 135° drill point gauge; use as a complementary layout tool for precise positioning.
HARFINGTON Drill Bit Angle Gauges
Best for precise angle readings across a wide range from 60° to 160°. Made of 2CR13 stainless steel, this gauge emphasizes anti-rust durability and easy readability with degree markings, useful for confirming 135° drill points and other common angles.
Limitation: It is a general-angle gauge, not exclusively a 135° point gauge; use it when you need a broad angle reference during setup.
Drill Gauge 3Pcs Angle Set
Best for quick checks across several standard angles including 135°. This set provides multiple angles in one compact package, helping users verify 135° as well as other common drill angles, making it versatile for teaching or workshop use.
Limitation: The description notes 118° and other apex degrees; verify that 135° is clearly represented on your model before purchase if this is a primary need.
Drill Bit Size Gauge With Angle Notch
Best for precise bit sizing with dedicated 118° and 135° notches for sharpening angles. The gauge uses etched holes from 1/16″ to 1/2″ for quick bit identification and includes angle notches to support sharpening and setting 135° angles on drill bits. Constructed from stainless steel for durability.
Caution: Not all versions clearly show a 135° notch on every listing; confirm the notch presence before relying on it for 135° work.
Buying Guide
What should I look for in a 135 degree drill point gauge?
Key features include durable material (stainless steel or cobalt-coated options), a clear 135° marking or notch, and compatibility with common drill sizes. A gauge that offers multiple angles is helpful for broader workshop use, but a dedicated 135° notch ensures quick checks for that exact point.
Is a dedicated 135° gauge better than a multi-angle tool?
A dedicated 135° gauge offers faster, more precise verification for that angle, reducing setup time. A multi-angle tool is valuable when your work requires frequent shifts between angles, but you may trade some speed for versatility.
Which materials improve gauge longevity?
Stainless steel resists rust and deformation, making it ideal for shop environments. Titanium-coated or cobalt alloys in drill bits are durable, but for gauges, stainless steel or hardened steel with a clear etched scale is typically preferred.
Can these gauges be used during sharpening?
Yes, several options include notches or markings that help align a drill bit edge to the desired angle during sharpening. Ensure you follow safe sharpening practices and use appropriate equipment for the bit type and material.
Which product is best for beginners?
The 3Pcs Angle Set offers a straightforward range of angles for learning and quick checks, making it a practical starting point. For more precise 135° tasks in metalworking, the cobalt bit set provides a robust primary tool.
Practical tips for choosing
- Match the gauge’s angle range to your most-used angles, including 135°.
- Prefer stainless steel with clear etched markings for longevity and readability.
- Consider a combination approach: a dedicated 135° gauge plus a multi-angle set for versatility.
- Check that the product includes an easily accessible 135° notch or marking for quick use.
FAQ
- What is the benefit of a 135° drill point gauge? It provides quick verification and sharpening alignment for drill bits to achieve consistent hole quality in metal or hard materials.
- Can I rely on a 135° gauge for all drill bits? It helps for typical twist drills where 135° is a standard point, but verify compatibility with special bits before use.
- Are all gauges made of stainless steel? Not all; some are stainless, others may be cobalt-coated or mixed materials. Stainless options are generally more durable for long-term use.
- Is it okay to use these gauges on handheld drills? Yes, when used as part of a careful setup and measurement process on a stable surface or stand.
- Should I buy a separate sharpener for 135° points? If you frequently work with 135° points, a dedicated sharpener can improve consistency and reduce drift compared to manual sharpening alone.
- Which is the best overall pick for a small shop? A combination approach often works best: a durable cobalt set for bit quality and a 135° dedicated gauge for quick angle checks.
