The Specialized Deep Hole Drilling System Type 07 represents a pinnacle of application-specific engineering within our range of Deep Hole Machining Solutions. Designed for demanding mid-to-large diameter applications (25.00 - 50.99 mm), this system transcends being a mere tool; it is a cohesive drilling solution that integrates a custom-ground tool body with a modular, replaceable-component architecture. It delivers the uncompromising accuracy and reliability that defines our premium line of Precision Gun Drills, while offering unparalleled cost efficiency over its lifecycle.

This system is engineered around a fundamental principle: maximum performance with minimum long-term cost. The core tool body is manufactured to your exact diameter specification, guaranteeing hole accuracy from the first operation. Paired with this custom body is an intelligent system of replaceable carbide blades and hardened guide strips. This hybrid approach ensures you invest once in the perfect size, and thereafter only in the small, wearable components. It is designed for seamless integration into modern BTA Drilling Systems, offering a plug-and-play solution for complex deep hole tasks.
Each system's diameter is final-ground during production to your specified tolerance (e.g., ±0.01 mm). This eliminates all variables associated with in-machine adjustments, shim packs, or wear-compensation mechanisms, delivering absolute consistency. This is a cornerstone of our philosophy for Precision Gun Drills.
This is our key differentiator. Competitors' solid tools require a full replacement when worn. Our system allows you to replace only the blades and strips (approximately 15-25% of the system's cost), protecting your capital investment in the custom-sized body indefinitely. The savings compound dramatically over time.
The system is engineered specifically for its diameter range. The solid body provides inherent rigidity, while the precisely fitted guide strips offer maximum bore contact and support, damping vibration and ensuring exceptional hole straightness and surface finish, even at high depths of cut.
The geometry of the cutting blades and the position of coolant outlets are calculated based on the target diameter and expected chip volume. This scientific design prevents chip jamming, reduces cutting forces, and protects both the workpiece and the tool, a critical aspect of advanced Deep Hole Machining Solutions.
This system excels in industries where precision, repeatability, and cost-control intersect:
Our manufacturing is governed by a certified quality management system. Every Specialized Type 07 system is born from fully traceable raw materials and undergoes a regimented production process. Final inspection utilizes high-precision CMM and surface finish measurement equipment, with results documented on a certificate of conformity that accompanies each shipment, assuring you of its performance pedigree.
While offering a standard platform, we excel at tailoring the Type 07 system to unique challenges:
Your system is crafted through a meticulous 7-stage process:
For standard configurations within the 25-51mm range, lead time is typically 4-6 weeks. Complex customizations may require additional engineering time. We provide a firm delivery schedule upon order confirmation.
We provide clear wear limits. For blades, monitor flank wear (VB); replace before it exceeds 0.3mm for finishing or 0.6mm for roughing. For guide strips, monitor hole diameter; replace if drift exceeds your part tolerance. Regular inspection is key.
It is optimized for dedicated deep hole drilling machines or lathes with high-pressure through-spindle coolant. While it can be used on a machining center with an external high-pressure system, stability and results are best on designed equipment.
Yes. For large orders or critical applications, we can arrange on-site technician support or comprehensive virtual training for your operators and programmers to ensure optimal results from your Deep Hole Drilling Tools investment.
We warrant the tool body against material and manufacturing defects for one year. The replaceable components are consumables. Our technical support is unlimited, providing assistance for parameter optimization, troubleshooting, and application advice.
