Exchangeable Tip Drill Selection — Quick Reference
Exchangeable tip drill systems = REUSABLE steel shank body + REPLACEABLE CARBIDE cutting TIP. When tip wears, only tip is replaced — shank body keeps going. Production drilling + extended tool life + lower per-hole cost vs solid drills.
| Component | Best For |
|---|---|
| Drill Body / Shank | Reusable mount — match to spindle/turret |
| Replaceable Carbide Tip | Consumable cutting edge — multiple sizes per body |
| Coolant-Through | Direct coolant + chip evacuation |
| Diameter Range (10mm-50mm typical) | Production sizing |
| Standard 118° Point | General materials |
| 135° Split Point | Self-centering + harder materials |
| Coated Tips (TiN / TiAlN) | Extended life + harder materials |
Critical: Exchangeable tip = PRODUCTION + CNC use — cost-effective beyond moderate hole volumes. Match tip + shank body system (proprietary fit). Brands: Seco, Maxigear. Companion: drilling, changeable drill bit sets, replaceable drill tips.
Exchangeable Tip Drills
Exchangeable tip drill systems combine a reusable steel shank body with a replaceable carbide cutting tip. When the tip wears, only the tip is replaced — the shank is retained and reused. This approach offers the performance of solid carbide at the cutting edge with a significantly lower replacement cost per hole compared to replacing a full solid carbide drill. Exchangeable tip drills are designed for use on CNC machining centres and rigid drilling machines where the consistent geometry of the replaceable tip can be relied upon. AIMS Industrial supplies exchangeable tip drills for CNC machining and high-production drilling applications.
How Exchangeable Tips Work
The carbide tip seats into a precision pocket at the end of the shank body and is secured by a clamping screw. Tip-to-shank interfaces are engineered for high runout accuracy — the tip must seat in exactly the same position each time it is replaced for the drill to maintain positional accuracy and diameter consistency in the machined hole. Quality exchangeable tip systems achieve runout performance comparable to solid carbide drills; inferior designs allow tip movement that produces oversized, out-of-round holes.
Advantages in High-Volume Production
In CNC production environments, the economics of exchangeable tip drills are compelling. A solid carbide drill in a production application may be replaced multiple times per shift. An exchangeable tip drill uses the same shank indefinitely — only the tip, which costs a fraction of the full drill, is consumed. Tool change time is also reduced: swapping a tip takes seconds without removing the shank from the tool holder, maintaining tool length offset consistency and eliminating the need to re-measure after tool changes.
Size Range and Compatibility
Exchangeable tip drill systems are available in diameter ranges typically from 12mm to 40mm — sizes where solid carbide drills are expensive enough that the tip-replacement economy becomes significant. Smaller diameter drilling (below 12mm) is generally performed with solid carbide or HSS drills, where the economics are different. Each manufacturer's tip interface is proprietary — tips and shanks must be from the same system.
Coolant-Through Design
Most exchangeable tip drill shanks are designed with through-spindle coolant channels that deliver coolant directly to the cutting tip. This is essential for deep-hole performance at the cutting speeds that justify using this tool type. Adequate coolant flow at the tip prevents heat build-up that would rapidly degrade even the toughest carbide tip.
