Typical Use Cases

• Electrical installation – cutting holes in consumer units, DBs, metal-clad boxes and trunking for
  cable glands, conduits and knockouts.
• Data & comms – forming precise entries in cabinets, racks and enclosures for cable management and glands.
• HVAC & mechanical – creating holes in ductwork, fan housings and light sheet metal for sensors, pipework and cable entries.
• Fabrication & panel work – fast, repeatable holes in thin sheet steel panels in the workshop or on site.

Installation & Application Tips

• Selecting the correct holesaw:
  • Choose the diameter to suit your gland, conduit, bush or fitting (check manufacturer’s recommended hole size).
  • Confirm the holesaw is an Armeg Acceler8% Sheet Steel variant for optimum performance in thin steel.
• Arbor & pilot drill:
  • Fit the holesaw to the correct size arbor (Armeg or compatible), ensuring the threads and drive pins are fully engaged.
  • Use a suitable pilot drill in the arbor to accurately locate the hole centre.
• Tool choice:
  • Use with a corded or cordless drill that has:
    • A variable speed control, and
    • A functioning safety clutch where possible.
  • Do not exceed the holesaw’s recommended maximum RPM (see product markings/datasheet).
• Cutting technique:
  • Clamp or support the workpiece securely to prevent movement.
  • Mark the centre point and centre punch if needed to help guide the pilot drill.
  • Start drilling at low speed to allow the pilot to engage and the teeth to start cutting cleanly.
  • Maintain a steady, even feed – do not force the holesaw; let the cutting edge work.
  • For thicker or harder steels, use a suitable cutting fluid/lubricant to improve life and cut quality.
• Slug removal & deburring:
  • After cutting, safely remove the slug/disc from inside the holesaw (disconnect the drill first).
  • Deburr the hole edges with a deburring tool or file to remove sharp burrs before fitting glands or components.
• Safety considerations:
  • Always wear safety glasses, gloves and hearing protection.
  • Beware of sharp swarf and hot edges on freshly cut metal.
  • Allow the holesaw and workpiece to cool between successive cuts when working continuously.

Frequently Asked Questions – Armeg Acceler8% Sheet Steel Holesaw

1. What thickness of steel can the Acceler8% Sheet Steel Holesaw cut?

The holesaw is designed for thin-gauge sheet steel and enclosure materials. Maximum recommended thickness
depends on the diameter and specific product. Always:

• Check the Armeg datasheet or packaging for the exact maximum cutting thickness, and
• Use suitable cutting fluid on harder/thicker materials to extend life.

2. Can I use this holesaw on stainless steel?

Some thin-gauge stainless enclosures may be drillable, but stainless is harder and more abrasive than mild steel.
For stainless:

• Check the Armeg technical guidance for stainless suitability, and
• Use slow speeds and appropriate lubricant if permitted.

For heavy or repeated cutting in stainless, consider specialist stainless-rated cutters.

3. What arbor do I need with the Armeg Acceler8% Sheet Steel Holesaw?

You’ll need a compatible holesaw arbor that matches:

• The holesaw’s thread size and drive configuration, and
• Your drill’s chuck size (e.g. 10 mm or 13 mm).

Armeg offers matched arbors for their holesaws; using the correct arbor ensures secure drive and alignment.

4. Can I use the holesaw in a cordless drill?

Yes, provided your cordless drill/driver:

• Has sufficient torque for the diameter and material,
• Has a variable speed setting to maintain appropriate RPM, and
• Is used with a fully charged battery and good technique.

For larger diameters or tougher materials, a more powerful corded drill may be preferable.

5. How can I get the cleanest possible hole in sheet metal?

For best results:

• Firmly support and clamp the workpiece,
• Centre punch and start at low speed,
• Maintain steady, moderate pressure,
• Use a cutting lubricant if appropriate, and
• Deburr both sides of the hole after cutting.

6. Common Uses & How to Use the Armeg Acceler8% Sheet Steel Holesaw

Common Uses:

• Cutting gland and conduit entry holes in steel trunking and control panels.
• Creating knockouts in metal consumer units and DBs where permitted.
• Forming cable and pipe access holes in light sheet metal enclosures.
• General sheet metal perforation in workshop and fabrication settings.

How to Use – Step-by-Step:

1. Select the correct holesaw diameter for your fitting (gland/conduit/etc.).
2. Fit the holesaw to the correct arbor, ensuring the threads are tight and the pilot drill is correctly installed.
3. Clamp or firmly secure the workpiece and mark the centre point of the hole.
4. Fit the arbor into your drill’s chuck and tighten securely.
5. Start drilling at low RPM to engage the pilot drill and start the cut, then increase speed within the recommended range.
6. Apply steady pressure and let the holesaw cut without forcing. Back off occasionally to clear swarf if necessary.
7. Once through, release the trigger and allow the tool to stop before withdrawing the holesaw from the workpiece.
8. Remove the slug from inside the holesaw and deburr the hole as required before fitting components.
