- Design: CNC-machined with 2 flats on the Weldon shank for secure clamping
- Edge quality: burr-free edges for smooth drilling
Best for: Heavy-duty projects requiring deeper 2″ cuts and secure clamping. Use steady pressure for best results. Consider this when you need larger hole depth in a single pass.
Limitation: Higher stiffness may require stronger drilling setup and stable workholding.
SALI Annular Cutter 13/16 in, 1″ Depth
- Size: Diameter 13/16″, cutting depth 1″, Weldon shank 3/4″, pilot pin 1/4″ x 3″
- Material: M48Al HSS for wear resistance and long service life
- Design: 3/4″ Weldon shank with 2 flats for secure grip
- Edge quality: burr-free, smooth hole surfaces
Best for: General purpose 1″ depth holes on magnetic drills. Choose this when depth is sufficient for most tasks and you want a balance of speed and control.
Limitation: Slightly shallower than the 2″ version; not ideal for deeper holes in one pass.
ANGELSWORD 13/16 in, 1″ Depth
- Size: Diameter 13/16″, cutting depth 1″, Weldon shank 3/4″
- Material: M2 high-speed steel (HSS) for wear resistance
- Design: CNC-machined with 3/4″ Weldon shank and 2 flats for secure clamping
- Edge quality: burr-free cuts with clean edge finish
Best for: Precision cuts with reliable edge finish in medium-depth holes. Suitable for applications requiring consistent performance and accuracy.
Limitation: Depth limited to 1″; not ideal for deeper drilling without changing to a deeper cutter.
S&F STEAD & FAST 13/16 in, 2″ Depth
- Diameter: 13/16″, cutting depth 2″, Weldon shank 3/4″ with 2 flats
- Material: M2AL HSS for durability and efficient cutting
- Design: CNC-machined with secure clamping features for burr-free holes
- Edge quality: smooth hole surfaces with consistent diameter
Best for: Deep-hole applications and projects requiring extended cutting depth in a single pass. Good for metal plates and structural work.
Limitation: Deeper cuts may demand steadier feed pressure to avoid deflection.
S&F STEAD & FAST 4-Piece Set, 13/16 x 2″
- Set includes 4 annular cutters, 13/16″ diameter, 2″ depth each
- Material: M2AL HSS for durability and long service life
- Shank: 3/4″ Weldon with 2 flats for secure clamping
- Edge quality: designed for burr-free holes and smooth finishes
Best for: Shops needing multiple 13/16″ cutters with consistent depth. Ideal for batch projects requiring interchangeable bits.
Limitation: The set concentrates on 2″ depth; if shallower cuts are needed, some bits may be underutilized.
OSCARBIDE 13/16 x 1″, 3/4″ Weldon
- Size: Diameter 13/16″, depth 1″, Weldon shank 3/4″ with 2 flats
- Material: HSS with dual alternating teeth for efficient cutting
- Design: 2-flat Weldon shank for secure clamping on mag drills
- Edge quality: burr-free, smooth holes with high accuracy
Best for: Balanced performance for general purpose 1″ depth tasks. Suitable when you need reliable, consistent cuts without deep drilling.
Limitation: Not the deepest option among 13/16″ cutters.
Buying Guide: Key Considerations for 13/16″ Mag Drill Bits
- Depth of cut: Choose a depth that matches your most common hole requirements. Deeper cuts enable fewer passes but demand steadier feeds and robust setup.
- Shank compatibility: All listed options use a 3/4″ Weldon shank with two flats. Verify your magnetic drill press accepts this shank and clamp style.
- Material and hardness: HSS (M2, M48AL) cutters provide wear resistance and longer life. Consider higher-grade alloys for tougher metals or frequent use.
- Pilot pin size and placement: Ensure your pilot pin matches your drill bit’s intended depth (3″ vs 4″ etc.) to improve hole alignment and reduce wander.
- Edge finish: Burr-free edges reduce finishing work and improve hole quality. Look for CNC-machined precision cuts for consistent results.
- Quantity vs. variety: Sets are beneficial for batch projects. Individual bits are better for dedicated, specific-depth tasks.
- Usage guidance: Maintain firm, steady pressure during cutting to improve results and prolong bit life.
- Compatibility with mag drill press: Ensure your machine can accommodate 13/16″ cutters and the required depth; verify clearance and workholding stability.
Frequently Asked Questions
- What is the standard diameter of a 13/16 inch mag drill bit?
Answer: The standard cutting diameter is 13/16 inches, with cutting depths typically 1″ or 2″ depending on the model. - What does Weldon shank mean, and why is it important?
Answer: A Weldon shank provides a flat-ground surface with flats for secure clamping, reducing slippage during drilling on mag drills. - Are deeper cutting depths better for all projects?
Answer: Not always. Deeper cuts require stable workholding and controlled feed to prevent deflection. Use the depth that matches the task. - Should I choose HSS over other steel types for annular cutters?
Answer: HSS (like M2, M48AL) offers good wear resistance and versatility for metal drilling; longer service life is typical with quality HSS. - Can I use a 13/16″ annular cutter for drilling thicker material?
Answer: Yes, when the cutter depth matches the material thickness and the drill press has adequate workholding and cooling, you can drill thicker plates in stages. - Is a 2″ depth cutter suitable for all mag drills?
Answer: It’s ideal for projects requiring deeper holes in a single pass, provided your setup supports it and you apply steady pressure.
