SPMG-QG Precision U Drill Inserts | High-Speed

About the product

High-precision processing: With high-precision cutting ability, it can achieve precise hole processing and ensure the size and shape accuracy of the hole.Strong durability: Made of carbide, it has good wear resistance and impact resistance, long service life, and can effectively reduce processing costs.

Wide range of applications: Suitable for processing a variety of materials to meet processing needs under different working conditions; it can not only be used for drilling, but also for boring, chamfering and other processing operations, which improves the utilization rate of the tool.

Economical and convenient: Multi-tip design, can be used 3-4 times, reduces the frequency of tool replacement and improves processing efficiency; 

discard design, no need to re-grind the blade after wear, just replace the new blade directly, simple and fast operation.Optimized cutting performance: large positive rake angle design, low cutting force, low vibration, low power consumption, can ensure the stability and accuracy of the processing process; unique groove design, easy chip removal, reduce the impact of chips on the tool and workpiece, improve processing efficiency and quality.

Material & Construction

• Substrate: Crafted from high-grade cemented carbide with a fine micrograin structure (grain size 1.0–1.5μm) and a cobalt binder content of 8–10%. This formulation delivers exceptional hardness (91–93 HRA) and toughness, ensuring superior wear resistance and impact resistance—critical for handling diverse materials from steel to titanium.

• Durability Enhancement: The carbide matrix is engineered to resist thermal fatigue and abrasive wear, even in high-speed drilling of hard materials like quenched and tempered steel, extending overall tool life.

• 
  

Key Features

• High-Precision Cutting: Designed for tight tolerance hole machining, achieving dimensional accuracy of ±0.01mm and shape precision (roundness ≤0.005mm). This ensures consistent hole size and geometry, eliminating the need for secondary finishing operations.

• Multi-Material Versatility: Efficiently processes a wide range of materials, including:

• Ferrous metals: Ordinary carbon steel, quenched and tempered steel (up to 45 HRC), and stainless steel (304, 316).

• Non-ferrous metals: Titanium and titanium alloys, aluminum alloys, and high-strength alloys.

• Multi-Functional Capability: Beyond drilling, supports secondary operations such as boring (to refine hole diameter) and chamfering (to deburr hole edges), maximizing tool utilization and reducing tool change downtime.

• Multi-Tip Design: Features 3–4 usable cutting edges per insert, allowing multiple indexing cycles before replacement. This reduces tool change frequency by 60–70% compared to single-tip inserts, boosting processing efficiency.

• Convenient Tool Change: Adopts a throwaway (indexable) design—no regrinding required after wear. Simply index to a new edge or replace with a fresh insert, minimizing setup time to under 2 minutes per change.

• Low Cutting Force & Vibration: Equipped with a large positive rake angle (+8°–+12°), reducing cutting forces by 20–30% compared to standard drill inserts. This minimizes machine vibration, lowers power consumption, and ensures stable, accurate machining even in thin-walled or delicate workpieces.

• Smooth Chip Evacuation: Integrates a unique spiral chip evacuation groove design that accelerates chip flow away from the cutting zone. This prevents chip entanglement, reduces friction between chips and the tool/workpiece, and improves surface finish quality (Ra ≤ 1.6μm) in drilled holes.

• 
  

Applications

• Primary Operations: High-precision drilling of through holes and blind holes, with compatibility for hole diameters ranging from 10mm to 50mm (depending on U drill body size).

• Secondary Operations: Boring for hole diameter refinement and chamfering (30°–45° angles) to remove burrs, ideal for automotive, aerospace, and mold & die components.

• Target Industries:

• Automotive: Drilling engine blocks, transmission housings, and suspension parts (steel/titanium components).

• Aerospace: Machining precision holes in titanium structural parts and stainless steel aircraft components.

• General Engineering: Fabricating industrial machinery parts requiring tight-tolerance holes in diverse materials.

Compatible Machines 

• CNC Machining Centers: Vertical machining centers (Haas VF-series, Mazak VTC), horizontal machining centers (DMG Mori NH-series), and 5-axis machining centers.

• CNC Lathes with Drilling Capability: Slant-bed lathes (Doosan Puma, Okuma LB series) equipped with turret-mounted U drill holders.

• High-Speed Machining Centers: Brother Speedio and Okuma HSC-series machines, leveraging the insert’s low vibration design for high-speed drilling (up to 3,000 RPM).

Usage method

Installation: Install the blade on the U drill cutter body to ensure a firm installation.

Debugging: Adjust cutting parameters such as cutting speed, feed rate, etc. according to processing materials and requirements.

Processing: Start the equipment, perform drilling or other processing operations, pay attention to the processing process, and ensure the processing quality and efficiency.Application scenarios

Mechanical processing: Applicable to drilling processing of various mechanical parts.

Automobile manufacturing: Widely used in automobile parts processing.

Aerospace: Applicable to high-precision processing requirements in the aerospace field.

Mold manufacturing: Meet the high-precision and high-durability requirements in mold processing.

Lifespan & Performance Metrics

• Cutting Parameters:

• Steel/Stainless Steel: Cutting speed 80–200 m/min; feed rate 0.1–0.3 mm/rev.

• Titanium Alloys: Cutting speed 40–100 m/min; feed rate 0.08–0.2 mm/rev.

• Service Life:

• 
  

• 150–250 holes per cutting edge on steel (depending on hole depth and material hardness).

• 80–150 holes per edge on abrasive stainless steel or titanium.

• Total lifespan across 3–4 edges: 450–1,000 holes, significantly reducing tooling costs per part.
