Product Introduction:
SL series deep-hole drill is one of our famous products which can deal with multiple operation, especial focus on deep-hole machining. Massive analysis of simulated cutting ensures the structure of SL series reaches the optimization. The double special guiding margin helps to achieve more credible guiding and more stable machining. The special design with change parameter helical flute has good rigidity and chip removal capabilities. Moreover, the unique cutting-edge design guarantees the excellent chip breaking capabilities, even for sticky, softer material. We also develop the special nano coating with better self-lubricating capability and superb wear resistance which significantly increase productivity and tool life.

Recommended Machining Method of SL series Deep-hole Drills:
Hole-guided Machining
● Apex angle of drills used for hole-guided machining has to be greater than the apex angle of deep-hole drills.
● Diameter of drills used for hole-guided machining has to be respectively greater than the diameter of deep-hole drills. Generally, the diameter range of deep-hole drills is between 0 and positive 0.1.
● Generally, the depth of pre-drilling hole is 1-3D (D is the diameter of pre-drilling holes). Also, it basically needs to ensure the accuracy of pre-drilling holes at the same time.
