MK Morse Introduces ORSY BOX Hole Saw Sets for Industrial Cutting

The kit's tooth geometry is designed to deliver rapid cutting progress under low thrust, lowering the physical effort required from the operator, according to the manufacturer. M. K. Morse said the design prioritizes concentricity and lateral stroke accuracy, allowing the tool to run smoothly with limited vibration through the full 38 mm cutting depth.

The company said the tool body has been reinforced, with additional threads in the base plate to increase connection strength under load. The configuration is positioned for repeated use in industrial assembly and precision machining environments, where consistent hole geometry and tool stability are critical.

• Material: M42 bi-metal with 8% cobalt, balancing hardness and toughness.
• Structure: Reinforced base plate with additional threads to strengthen the connection.
• Stability: Concentricity control intended to limit vibration during operation.

The set is listed as compatible with a range of metals and non-metals, making it suitable for metalworking and assembly tasks. According to the manufacturer, it can be used on steel, stainless steel, cast iron, copper, bronze and aluminum, as well as on wood and plastics.

Note: For frequent high-intensity work in steel and stainless steel, the company recommends its HW series of carbide-tipped hole saws. The ORSY BOX set is not intended for very thin metal sheet.

The manufacturer specifies four operating steps intended to support tool life and cut quality:

1. Pre-drilling: Apply light contact pressure during the initial cut to ensure accurate positioning.
2. Constant pressure: Maintain minimal, even pressure while drilling and avoid wobbling, which can damage the teeth.
3. Cooling and lubrication: Follow the supplied speed chart and use coolant to reduce cutting heat.
4. Chip clearance and cooling: When working wood and wood-alternative materials, periodically withdraw the hole saw to clear chips and allow the cutter to cool.

The company said operators should adhere strictly to the speed chart, since hardness and thermal conductivity vary by material. Correct rotational speed combined with coolant is described as essential to cutting efficiency and dimensional accuracy.
