Ruilif Tools Expands Back-Pull Modular Drill Series with 11.00–11.90 mm Sizes

Release Time:

May 20,2026

Ruilif announces ten additional back-pull modular drill sizes from 11.00 to 11.90 mm, extending the announced series range to 11.00–52.00 mm.

Ten Additional Small-Diameter Sizes

Ruilif Tools (Qingdao) Co., Ltd. has expanded its back-pull modular drill series with ten sizes from 11.00 mm to 11.90 mm. As announced in this product update, the series range extends from 11.00 mm to 52.00 mm.

The additional nominal diameters are:

  • 11.00 mm, 11.10 mm, 11.20 mm, 11.30 mm and 11.40 mm.
  • 11.50 mm, 11.60 mm, 11.70 mm, 11.80 mm and 11.90 mm.

Confirm the Complete Assembly

The modular design uses a replaceable cutting component with its compatible drill body. Diameter is only one selection requirement. Confirm the body series, usable drilling length, shank connection and cutting-component code before placing an order. Components should not be treated as interchangeable solely because their nominal diameters match.

Review the Intended Application

For automotive parts, precision components and other metal hole machining work, provide the material grade and condition, hole depth, tolerance, machine setup and coolant arrangement. Suitability and starting cutting data must be confirmed for the selected assembly. A new size option does not by itself demonstrate a particular surface finish, tool life or deep-hole capability.

Compare Production Value with Actual Results

Replaceable components allow the body and cutting element to be considered separately in tooling planning. The practical result depends on replacement time, body condition, accepted-hole quality and component life. Evaluate these factors in a representative application rather than assuming automatic savings from the modular format.

Conclusion

The added sizes expand the options described in this announcement. For current specifications and availability, review the modular drill system and confirm the required body and cutting component with Ruilif.
