SP 3XD High precision Drill insert
Indexable drills Overview
The SP 3XD is a high-performance indexable drill insert engineered for precision hole-making in a wide range of materials. Designed as a cost-effective alternative to solid carbide drills, this insert delivers excellent cutting accuracy, long tool life, and operational flexibility for modern machining workshops.
Detailed description of indexable drill bits
The SP 3XD series represents a modular drilling solution that combines interchangeability with high precision. Unlike monolithic carbide drills that require full replacement when worn, this indexable insert system allows users to quickly swap out dull or damaged cutting edges, significantly reducing per-hole tooling costs and machine downtime.
How WC and SP are classified
Key Features and Engineering Benefits
Interchangeable Insert Design – The SP 3XD uses replaceable cutting inserts that can be indexed or changed in seconds. This feature extends the usable life of the drill body and lowers long-term tooling expenses compared to solid carbide alternatives.
Versatile Material Compatibility – Suitable for drilling metals (steel, stainless steel, cast iron, aluminum alloys), plastics, and composite materials. The insert geometry is optimized for both through-hole and blind-hole applications.
Modular Construction – The system offers flexible shank options, coolant delivery configurations, and body lengths, allowing users to tailor the tool to specific machine requirements and workpiece geometries.
High Accuracy and Surface Finish – Precision-ground cutting edges and strict tolerance control ensure consistent hole diameter, straightness, and surface quality, meeting the demands of aerospace, automotive, and general engineering sectors.
Integrated Coolant Channels – Built-in coolant supply directs fluid directly to the cutting zone, effectively reducing heat buildup and friction. This prolongs insert life, improves chip evacuation, and maintains cutting performance in deep-hole drilling.
Productivity Enhancement – Reduced tool change frequency and stable cutting behavior translate to less unplanned downtime, higher spindle utilization, and improved overall equipment effectiveness.
ADVANTAGE
Classification Insight: WC vs. SP Series
In our product family, the WC series typically targets general-purpose drilling, while the SP series is specifically refined for high-precision and high-efficiency operations. The SP 3XD, in particular, features an advanced substrate and coating technology that offers superior wear resistance and thermal stability under demanding cutting conditions.
Indexable drills Advantages
Cost per hole significantly lower than solid carbide drills
Quick indexability minimizes machine idle time
Consistent hole quality across batch production
Suitable for both manual tool change and automated tooling systems

FAQ
A: It is suitable for steel, stainless steel, cast iron, aluminum, copper alloys, plastics, and composites. For specific grades, consult our application engineers.
A: The SP series is designed for higher precision and more demanding surface finish requirements, while the WC series offers a broader general-purpose range.
A: Interchangeability depends on insert size and clamping system. We recommend using our matched drill bodies for optimal performance, but we can advise on compatibility.
A: Emulsion or soluble oil coolants are generally suitable. Through-coolant application is strongly recommended for deep-hole drilling.
A: Yes, we provide customized coatings (e.g., TiAlN, AlCrN) and edge treatments based on your specific workpiece material and operating conditions.
A: Standard inserts are available from stock. Custom orders require 2–3 weeks depending on quantity and specification.
