Triumph Twist Drill’s jobber length fractional drill bit is made from High Speed Steel with a 135° self-centering point, engineered for clean, accurate drilling in the demanding applications encountered in gunsmithing and general shop work. Special point and surface treatments give easier, more wear-resistant drilling of the tough steels encountered in the gun shop. The 35/64″ (.5469″) diameter size fills a critical gap in fractional drill progression, making it an essential tool for precise gunsmithing work.
All drills are made from High Speed Steel and engineered to deliver durability and longevity across repeated drilling cycles. The jobber length provides the versatility needed for both general-purpose drilling and specialized gunsmith applications where accuracy and repeatability are non-negotiable.
