Technical Q&A
HSS Twist Drills & Materials
8 practical questions for product selection, sourcing and supplier evaluation.
What are HSS Twist Drills?
HSS Twist Drills are versatile cutting tools designed for precise holes in metal, wood, plastic and composites. Jiateng Tools lists M2, M35 and M42 among the HSS grades used across this range.
Which HSS grades are listed for the Jiateng drill range?
The current Jiateng Tools HSS range lists M2, M35 and M42. The suitable grade should be selected according to the workpiece, cutting conditions, expected service life and target price.
How should I choose between M2, M35 and M42?
M2 is a practical general-purpose industrial HSS. M35 is a cobalt-bearing HSS, commonly used when higher cutting temperature and harder workpieces require greater hot hardness. M42 is a more highly alloyed cobalt HSS for demanding heat- and wear-intensive applications. Final selection should be confirmed by the real application and sample testing.
Is M35 the same as a titanium-coated M2 drill?
No. M35 is a cobalt-bearing high-speed steel grade, while titanium coating is a surface treatment. The base steel grade and the coating should be specified separately.
What is the difference between roll forged and fully ground HSS drills?
They are different manufacturing routes that can affect geometry, accuracy, surface condition and cost. The better choice depends on the drilling application and the buyer's performance target.
What materials are HSS Twist Drills used for?
The Jiateng Tools catalogue positions HSS Twist Drills for drilling metal, wood, plastic and composite materials. The exact HSS grade, point geometry and finish should be matched to the workpiece and cutting conditions.
What point angles are used in HSS drill programmes?
Jiateng's current product and manufacturing content includes 118-degree and 135-degree point configurations. A 135-degree split point can improve centering and chip breaking in suitable applications, while the final point design should be confirmed against the workpiece and drilling conditions.
What is the difference between DIN 338, DIN 340 and DIN 1897?
Jiateng positions DIN 338 as a jobber-length drill programme, DIN 340 as a long-series programme for deeper holes or extended reach, and DIN 1897 as a stub-length programme for greater rigidity and controlled drilling.
