Fintro – Pen-Grip Precision Rotary Tool Kit

Steady hands, tiny holes, zero ruined pieces

You know how hard it is to drill a tiny hole without ruining the piece.

One slip and eight months of saving that project idea is gone.

That grip moves the control from your wrist to your fingertips — the same fingers that have written neatly your whole life.

Shells, beads, wood, resin. Clean holes, first try.

One of our most reordered craft tools this season

✓ Drill beads without holding your breath
The pen shape rests between your fingers, so small movements stay small. No wrist swing, no sudden bite into the material.

✓ One tool for 4 craft materials
Works on shells, wood, resin, and soft metal. Drill, sand, polish, and engrave without swapping to a bigger machine.

✓ Brass collet grips bits tight, no wobble
The metal collet holds standard 3.0mm bits square and steady. That's what keeps your line straight and your hole round.

✓ Light enough for long sessions
Slim aluminum body you can hold for an hour. Your hand won't cramp halfway through the fun part.

Bring Fintro to your craft desk today, and start drilling clean holes on the first try.

Can I use it on glass or stone?
Yes, with the right bit and a slow, steady pass. Let the tool do the work instead of pressing down — pressure is what cracks brittle material.

Do I need to buy special bits?
No. It takes standard 3.0mm shank bits, so you can pick up extras almost anywhere craft or hardware supplies are sold.

Is it loud enough to bother people in the same room?
It runs quieter than a full-size rotary tool. Most people describe it as a soft hum, not a whine.

Will it stall if I push too hard?
Push too hard and it will slow down — that's by design. Ease off and let the bit cut, and it keeps a steady speed.

How to use

• Step 1: Charge by USB before the first use. Give it a full charge so speed stays even.
• Step 2: Loosen the collet, slide in the bit, and tighten by hand until snug. A loose bit is what causes wobble.
• Step 3: Hold it like a pen and rest your hand on the table. Let the bit touch the material with almost no pressure.
• Step 4: Move slowly and let the tool cut. One or two light passes beat one hard push every time.

• Size: Slim pen-style body, sized to be held in one hand
• Material: Aluminum body with brass collet

In the box

• Fintro Mini Rotary Tool Pen, USB charging cable, and bit set
