Foredom H.20 vs H.28 Handpieces: Which Collet Setup Fits Your Work

Compare the quick-change Foredom H.20 and the collet-style H.28 on grip, bit changes, and runout, so you can pick the flex shaft handpiece that matches your jewelry work.
Quick answer
Choose the Foredom H.20 if you change burs constantly and want a fast, keyless quick-change handpiece for fine carving and engraving. Choose the Foredom H.28 if precision and minimal runout matter more than speed, especially for long high-speed sessions in a slim pencil grip.
The core trade-off: speed of change vs. precision of hold
The H.20 is built around quick-change operation: no chuck keys or wrenches, just a flip to swap burs. That saves time on jobs with many bit changes, but it is a different holding mechanism than a collet.
The H.28 uses 3/32" and 1/8" collets and a pin and chuck wrench. Collet-type handpieces such as this one offer the least runout of any flex shaft handpiece, which is why it suits precise work where a bit must run true.
Grip and comfort over long sessions
The H.20 is ergonomically sized and can be held almost any way, with a special nylon tip that allows a pencil grip. That flexibility helps when you rotate the handpiece through different angles on intricate carving.
The H.28 is a slim-line housing only 1/2" thick, shaped to reduce stiffness and cramping during hours of high-speed continuous use. If you already know you prefer a thin pencil grip, the H.28 is the more targeted shape.
When the catalog leaves a question open
The supplied facts do not list bur-holding capacity beyond the H.28's 3/32" and 1/8" collets, nor do they give speed ratings or warranty terms for either handpiece. If your work depends on a specific bit shank size or a particular motor pairing, confirm that detail before buying rather than assuming it.
Decision rules for each handpiece
- If you change burs often: Pick the H.20: its quick-change mechanism removes the need for chuck keys or wrenches, so bit swaps are a flip rather than a tooled step.
- If precision is the priority: Pick the H.28: its collet design is the least-runout option in the Foredom flex shaft line, which supports accurate work with 3/32" and 1/8" shanks. Keep the pin and chuck wrench handy; collet changes are tooled, not keyless.
- If long high-speed sessions cause hand fatigue: Weigh the H.28's 1/2"-thick slim-line housing against the H.20's ergonomic body and nylon pencil-grip tip, and choose the shape that matches how you actually hold the tool.
