| 1 | Fixed-Pitch Multi-Spindle Drill | 2–64 spindles, depending on head design | Commonly about Ø3–30 mm in metalworking configurations | Drills several holes simultaneously in a repeatable pattern; well suited to recurring jobs. | Flanges, plates, brackets, and components with consistent hole spacing | Best for stable hole patterns; changing pitch usually requires head or tooling adjustment. |
| 2 | Variable-Pitch Multi-Spindle Drill | Typically 2–20 adjustable spindles | Often about Ø3–25 mm, subject to spindle and material limits | Can machine multiple holes in one cycle while accommodating different layouts between setups. | Short-run parts, panels, fittings, and varied hole patterns | Check adjustment range, minimum spindle spacing, and setup time. |
| 3 | CNC Multi-Spindle Drilling Center | Commonly 4–16 controlled drilling positions or spindles | Often about Ø2–20 mm; configuration dependent | Automates programmed positioning and repeatable multi-hole operations; cycle time varies with travel and tool changes. | Machined plates, housings, automotive parts, and mixed-pattern components | Compare axis travel, programming capability, tool management, and workholding. |
| 4 | Vertical Multi-Spindle Drill | Usually 2–64 spindles across different head sizes | Commonly about Ø3–30 mm in metalworking use | Vertical feed supports batch drilling from above; simultaneous hole count depends on the head layout. | Flat workpieces, castings, fixtures, and components with top-facing holes | Allow for chip clearance, clamping access, and workpiece loading. |
| 5 | Horizontal Multi-Spindle Drill | Typically 2–32 spindles per drilling head or station | Often about Ø3–25 mm, depending on material and spindle power | Processes side-facing holes in one or more directions; can be integrated into transfer or assembly lines. | Frames, blocks, profiles, and parts requiring side drilling | Confirm access to the drilling face and the required fixture orientation. |
| 6 | Opposed-Side Multi-Spindle Drilling Machine | Multiple heads, often 2–24 spindles per side | Commonly about Ø3–20 mm in typical metalworking setups | Drills from opposing faces in the same clamping cycle, reducing repositioning for suitable parts. | Blocks, structural components, and parts with aligned or opposing holes | Evaluate alignment requirements, clamping rigidity, and chip evacuation on both sides. |
| 7 | Gang Drilling Machine | Often 4–8 separate drilling heads arranged in sequence | Commonly about Ø3–16 mm, depending on the spindle units | Operators can perform successive drilling or related operations without repeatedly changing tools at one spindle. | Small and medium batches requiring several drilling steps | Consider operator workflow, station spacing, and whether heads run independently. |
| 8 | Multi-Station Drilling Line | Several stations; total spindle count is engineered for the part | Typically designed around the required hole sizes and part geometry | Combines operations across stations and is suited to continuous, high-volume production; output depends on line balance. | Repeat-production components with several drilling operations | Assess automation, changeover strategy, maintenance access, and bottleneck cycle time. |
| 9 | Woodworking Multi-Boring Machine | Commonly configured with 21 or more boring spindles | Often uses small-diameter bits, roughly Ø3–10 mm; many systems use 32 mm hole spacing | Bores multiple furniture holes in one clamping operation; throughput depends on loading and panel handling. | Cabinet sides, shelves, furniture panels, and hardware mounting patterns | Check panel size, boring direction, row spacing, and required 32 mm system compatibility. |
| 10 | Tube and Profile Multi-Hole Drilling Station | One or more heads; spindle quantity is matched to the hole pattern | Hole range is highly dependent on tube wall, profile shape, and tooling | Purpose-built fixtures support repeatable hole patterns on long or shaped stock; automatic feeding can reduce handling. | Rails, frames, furniture tubes, and structural or industrial profiles | Verify profile support, rotation control, length capacity, and internal chip management. |
