Dental Handpiece

We have been manufacturing machined parts used in high-Speed dental handpieces. The high-quality metal parts meet the requirements of ultra-high-speed rotation performance and longer rolling life.

Machined parts for Dental Appliances

Dental handpieces are an essential tool in any practice. They are used by dentists, hygienists, specialists and lab technicians. A handpiece combines with several metal components and motors. Each component requires precise dimension for high reliability and performance or it may increase vibrations and abnormal noises in dental handpieces and eventually cause defects such as reduced rpm levels. Boly has been developing and manufacturing machined parts used in high-Speed (Air-Turbine) handpieces, electric handpieces, surgical handpieces, and implant handpieces. The high-quality metal parts meet the requirements of ultra-high-speed rotation performance and longer rolling life.

Stainless steel is most often used for Dental components, but others include nickel alloy and aluminum.

Material selectionWhat Specialty Materials Work Best for Dental Handpiece Components?

  • Stainless Steel and Specialty Steel
  • Aluminum Alloys
  • Nickel and High Temperature Alloys
  • Copper Alloys

Stainless Steel and Specialty Steel 

Stainless steel is ideal for dental instruments because it is strong and tough, lessening the likelihood of the instrument breaking. Due to the high hardness of surgical stainless steel, the tip life is prolonged and maintenance time is reduced.

Below are some of the grades in stock:
AISI 303
AISI 304
AISI 316
AISI 630

Aluminum Alloys

There is a great deal of aluminum alloys in Dental handpieces. Most aluminum alloys offer high weight to strength rations, corrosion resistance, formability, and favorable pricing.

Below are some of the grades in stock:
Aluminum 2011
Aluminum 4032
Aluminum 6061
Aluminum 6063
Aluminum 7075-T7651

Nickel and High Temperature Alloys

Nickel alloys have found increasing usage in Dental components that require great strength but can handle the increased weight. The high corrosion and temperature resistances found in Nickel alloy make it suitable for a range of Dental parts, including spindle, housing and coupling components.

Below are some of the grades in stock:
Nickel-Chromium Alloys – Inconel®
Inconel 600
Inconel 617
Inconel 625
Inconel 718

Nickel-Molybdenum-Chromium Alloys – Hastelloy®
Hastelloy C276

Copper Alloys

With copper’s outstanding conductivity, it ensures that the device is compliant with industry standards. It is widely used for handpieces motors and bushings.

Below are some of the grades in stock:
Copper C3600
Copper C3602
Copper C3604
Copper C4926 (Lead Free)
