Bullet Points

1. Optimized Spiral Flute for Efficient Chip Removal

Adopts widened and deepened spiral flute structure with larger chip holding space. It ensures smooth chip evacuation in vertical deep hole processing, avoids clogging, and improves chip removal efficiency by 40% compared with straight flute drills. Stable continuous cutting without tool breakage.

2. Side Lock Structure for Stable Clamping

Standard SL side lock shank with screw locking design provides uniform clamping force. No shank shaking or slipping under high-speed and high-feed cutting. It effectively prevents hole deviation and surface scratching, ensuring high processing consistency.

3. Indexable Replaceable Insert Design, Cost Saving

The drill shank is high-strength and reusable for long-term service. Only worn inserts need to be replaced instead of the whole tool. One shank matches multiple insert sizes, reducing tool inventory and procurement costs significantly.

4. Full Through Internal Coolant System

Built-in high-pressure coolant hole delivers cutting fluid directly to the cutting edge to quickly take away heat and chips. It prevents insert burning and workpiece annealing, extends tool service life by more than 30%, and improves hole surface finish.

5. High Precision 30D Deep Hole Machining

Symmetrical double-edge cutting structure ensures stable drilling. Hole tolerance ≤0.01mm, surface roughness Ra1.6-Ra3.2. It supports 30 times diameter ultra-deep hole drilling and fits carbon steel, stainless steel, cast iron, aluminum and copper alloy processing.

Applications

Widely used in deep hole drilling for auto parts, mold manufacturing, aerospace, construction machinery, 3C precision components and mechanical hardware. It can replace traditional twist drills, U drills and gun drills, perfectly suitable for mass production and high-precision deep hole processing scenarios.

Hot Q&A

Q1: What are the advantages of spiral flute spade drill over straight flute type?
A: The widened and deepened spiral flute provides larger chip holding space, ensuring smooth chip removal in vertical deep hole machining. It effectively avoids chip clogging and tool burning, improves chip removal efficiency by 40%, and supports continuous high-speed mass production with higher stability and efficiency.
Q2: Will the side lock shank slip or deviate during cutting?
A: No slipping or shaking. The standard SL side screw locking structure provides uniform clamping force. It maintains stable performance under high-speed and high-feed cutting, controls hole deviation accurately, and ensures consistent processing quality for batch production.
Q3: What is the maximum drilling depth and applicable materials?
A: It supports max 30D ultra-deep hole drilling with hole tolerance ≤0.01mm and surface roughness Ra1.6-Ra3.2. It is suitable for carbon steel, stainless steel, cast iron, aluminum alloy, copper alloy and other metal materials for precision drilling.
