Overview
The DN Solutions PUMA DNT 2100 M is the 8-inch chuck mill-turn variant in the compact DNT 2100 series — a bread-and-butter production lathe for shops running small to mid-size parts with milling capability. If you need to drill cross-holes, tap ports, or mill flats on turned parts without pulling them for a second op on a VMC, the DNT 2100 M is designed exactly for that workflow.
The main spindle delivers 18.5 kW (24.8 hp) with 328 Nm (242 ft-lb) of torque at up to 4,500 RPM. That's a well-balanced combination for turning steel, stainless, and aluminum in the 8-inch chuck range. The 12-station turret runs live tools at 6,000-10,000 RPM — that's notably faster than the larger PUMA machines and lets you push milling and drilling operations harder on small features.
Max turning diameter is 320 mm (12.6 in) with 513 mm (20.2 in) of turning length. X-axis travel is 230 mm (9 in) and Z-axis provides 580 mm (22.8 in). Rapids hit 24 m/min on X and 30 m/min on Z — significantly faster than the big-bore PUMA 4100/5100 machines, which makes sense for a machine focused on shorter cycle times on smaller parts.
The DNT designation represents the newest generation in the PUMA turning lineup, replacing the older GT and standard PUMA models. It brings improved thermal compensation, refined servo tuning, and the updated FANUC 0i-TF Plus control with modern HMI features. The machine weighs 3,800 kg (8,377 lb) and measures 2,945 mm (116 in) long — a manageable footprint for most shops.
At this price point and capability level, the DNT 2100 M competes directly with the Haas ST-20Y, Mazak Quick Turn 200MY, and Okuma LB2000 EX II. It's a high-volume production machine that also works well in job shops needing versatile turn-mill capability. Specs sourced from DN Solutions published data.

Strengths & Limitations
Strengths
- 6,000-10,000 RPM live tooling is the fastest in the PUMA lineup — excellent for milling and drilling on small parts
- 24/30 m/min rapids keep cycle times low on high-volume production runs
- 8-inch chuck and 4,500 RPM spindle balance versatility for steel, stainless, and aluminum work
- Compact 2,945 mm footprint fits into most shop layouts without major rearrangement
- Latest DNT generation with improved thermal compensation and updated FANUC 0i-TF Plus control
- Competitive price point against Haas ST-20Y, Mazak QT-200MY, and Okuma LB2000 EX II
- 3,800 kg weight doesn't require heavy-duty foundation — standard 150 mm concrete is typically sufficient
Limitations
- 18.5 kW (24.8 hp) spindle power is modest — heavy roughing in tough materials requires conservative feeds
- 320 mm max turning diameter limits the size of parts you can swing
- 513 mm turning length won't accommodate longer shaft work — check the 2600 series for that
- No sub-spindle standard — you'll need the MS variant for done-in-one parts
- No Y-axis on the base M model — off-center work uses C-axis interpolation only

Frequently Asked Questions
01
The M uses an 8-inch chuck at 4,500 RPM with 328 Nm torque. The MB uses a 10-inch chuck at 3,500 RPM with 403 Nm torque. Choose the M for smaller parts where higher spindle speed helps cycle time. Choose the MB when you need to clamp larger-diameter stock and want more torque for heavy cuts.
02
The DNT 2100 M has similar turning capability and price range. The Haas ST-20Y includes a Y-axis for off-center work, which the base DNT 2100 M lacks. However, the DNT's live tooling runs at 6,000-10,000 RPM versus the Haas's 4,000 RPM, giving it an edge on milling and drilling cycle times. The DN Solutions typically has an edge in turning rigidity.
03
Yes. Bar feeder integration is a common option for unattended production. The 8-inch chuck and through-bore accommodate standard bar stock sizes. Popular bar feeder brands like LNS, Iemca, and Fedek all offer compatible models. This is one of the best setups for high-volume bar work in the 8-inch chuck class.
04
The standard live tooling configuration runs at 6,000 RPM. An optional high-speed live tool spindle reaches 10,000 RPM for smaller endmills and drill bits where higher speed improves finish and extends tool life. The high-speed option adds cost but makes a noticeable difference on small features.
05
It's an excellent choice for shops moving up from manual lathes or adding their first production-grade turning center. The FANUC control is the most widely taught and supported in the industry. The 8-inch chuck is versatile enough for most general work, and the live tooling adds capability you'll appreciate as you grow.
