Arrowmax SDS ULTRA PLUS Mini Drill Pen

The Arrowmax SDS ULTRA PLUS is a compact electric mini drill pen designed for precision work on materials such as wood and acrylic. It delivers adjustable speeds from 400RPM to 700RPM with 2.3 kgf.cm of torque. The kit includes a Hedgehog benchtop press, ten HSS titanium-coated bits, and a CNC alloy storage box. It suits hobbyists and makers who need a portable drilling solution with a built-in press stand.

Check Power Needs and Bit Compatibility

Verify that your projects only require the supplied 3/32-inch keyless chuck capacity before ordering. The integrated 500mAh LiPo battery charges via USB-C and runs for up to three hours per charge. Ensure you have a USB-C power source available for recharging. The press adjusts bit-to-plate height from 33mm to 83mm, so confirm this range covers your workpiece thickness.

Upgrades Hand-Held Drilling with a Benchtop Press

This kit replaces a basic hand drill by adding a stable benchtop press with 360-degree rotation and preset angles of 15, 30, 45, 90, and 180 degrees. The jump is worth it when you need repeatable perpendicular holes or angled drilling without hand fatigue. The OLED display adds real-time charging status absent on simpler pens. It is not for users who need larger chuck sizes or continuous heavy-duty drilling beyond the 700RPM limit.

Questions about this item

What comes in the box and what must I buy separately?

The set includes the SDS ULTRA PLUS mini drill pen, the Hedgehog benchtop press with CNC aluminium disc, an alloy storage box, and 10 HSS titanium-coated drill bits. No extra items are required to start drilling.

Which speed setting should I choose for wood versus acrylic?

Use the 700 RPM top speed for faster drilling in wood, and drop to 400 RPM for finer control in acrylic; the four selectable speeds cover both materials.

How does the 2.3 kgf.cm torque perform when the pen is mounted in the press?

The 2.3 kgf.cm torque drives the 3/32-inch keyless chuck through wood and acrylic at the chosen speed, while the press holds the bit perpendicular and adjusts height from 33 mm to 83 mm for consistent depth.
