Tooltos DKJ-A Pearl Drilling Machine | 0.5-1.2mm, 4-35mm Beads, Foot Pedal
- 94 in stock
Description
Key Selling Points
- Drills holes from 0.5mm to 1.2mm in beads from 4mm to 35mm diameter — covers the full range of pearl, gemstone, and bead sizes used in jewelry production
- 16 pairs of collets (brass and plastic) accommodate round, olive, irregular, and shaped beads — no need to switch machines for different bead shapes
- Adjustable drilling depth prevents drilling through the bead — set the depth once and drill consistently across the entire batch
- Built-in dust box with dust hole at the base collects pearl powder and debris during batch drilling — clean out periodically to keep the drill bit running freely
- Foot pedal switch controls the motor hands-free — both hands stay on the bead for accurate positioning while the foot manages power
- 500-15000RPM variable speed (60-360W) adapts to different bead materials — lower speeds for soft materials like amber and beeswax, higher speeds for harder beads
About This Drilling Machine
Drilling pearls and beads by hand is slow, imprecise, and hard on drill bits. The drill tends to wander on curved surfaces, holes come out off-center, and without depth control you risk drilling through the bead entirely. For batch production — stringing a full necklace or bracelet — the inconsistency compounds across every piece.
The Tooltos DKJ-A Pearl Drilling Machine addresses each of these problems. The collet system holds the bead securely in position so the drill enters at the correct point every time. The adjustable depth stop prevents over-drilling. The foot pedal keeps both hands on the bead for accurate placement. And the built-in dust box manages the pearl powder that accumulates during batch drilling — a practical detail that matters when you are drilling dozens of beads in a session and need the drill path to stay clear throughout.
Compatible Bead Materials
| Material | Recommended Speed | Notes |
|---|---|---|
| Freshwater and saltwater pearls | Medium to high | Clean dust box frequently — pearl powder accumulates quickly |
| Amber, beeswax | Low to medium | Soft material — lower speed prevents melting and bit binding |
| Wood beads, rosaries | Medium | Consistent speed for clean entry and exit holes |
| Ivory, bone | Medium to high | Harder material — higher speed for efficient cutting |
Best For / Not For
| Best For | Not For |
|---|---|
| Pearl and bead jewelry producers drilling batches of 4-35mm round, olive, or irregular beads | Holes larger than 1.2mm — this machine drills 0.5-1.2mm holes only |
| Jewelry studios needing consistent hole placement and depth across large batches | Beads smaller than 4mm or larger than 35mm — outside the collet clamping range |
| Stringing artisans working with pearls, amber, beeswax, wood beads, and rosaries | Drilling metal, stone, or ceramic — this machine is designed for organic and soft bead materials |
| Workshops needing foot pedal control for hands-free speed management during precision drilling | Replacement drill bits not included — the 10 included bits are consumables that will need replacement |

Pro Tips
- Clean the dust box after every 20-30 pearls during batch drilling — accumulated pearl powder compresses and can cause the drill bit to bind and break before it completes the hole.
- Set the depth stop on a test bead before starting a batch — verify the hole depth is correct before committing to the full run, as adjusting mid-batch wastes time and risks inconsistent results.
- Use the plastic collets for softer beads (amber, beeswax, soft pearls) and the brass collets for harder or heavier beads — plastic collets grip without marking soft surfaces.
- Start at a lower speed and increase gradually for each new bead material — different materials respond differently to drill speed, and starting slow lets you find the optimal speed without breaking bits.
- Keep spare drill bits on hand before starting a large batch — the included bits are consumables and fine bits (0.5-0.8mm) break more easily than larger sizes, especially in harder materials.
Frequently Asked Questions
What is the smallest and largest bead this machine can drill?
The collet clamping range is 4mm to 35mm diameter. Beads outside this range cannot be securely held in the collet system and should not be drilled with this machine.
What hole sizes can this machine drill?
The machine drills holes from 0.5mm to 1.2mm using the included drill bits. For holes larger than 1.2mm, a different drilling machine is required.
Are replacement drill bits included?
10 drill bits are included. These are consumables that will wear with use, particularly the finer sizes. Replacement bits in the 0.5-1.2mm range must be sourced separately when the included bits are depleted.
Can this machine drill half-holes (for half-drilled pearls)?
Yes. The adjustable depth stop lets you set a specific drilling depth, which allows you to drill half-holes for half-drilled pearl applications such as earring posts and pendant caps.
Can this machine drill stone or ceramic beads?
This machine is designed for organic and soft bead materials — pearls, amber, beeswax, wood, ivory, and bone. It is not designed for drilling stone, ceramic, or metal beads, which require diamond-tipped bits and different machine specifications.
