Cutting Tools

Product Details:

HSS (High-Speed Steel) Parallel Shank Twist Drills are versatile, durable cutting tools with a cylindrical, straight shank used primarily for precision drilling in metal, wood, and plastic. Featuring two helical flutes, these hardened, ground bits offer excellent heat resistance, with common designs including a 118° or 135° point angle for efficient chip removal. 

Key Features and Specifications:

• Material: Constructed from high-speed steel (HSS), ensuring durability, high wear resistance, and the ability to maintain sharpness at high cutting temperatures.
• Shank Type: Parallel (or straight) shank, where the shank diameter is generally the same as the cutting diameter, suitable for standard chucks.
• Design: Typically feature two helical flutes for efficient chip removal and a 118° or 135° point angle for quick, self-centering, and precise drilling.
• Applications: Ideal for general-purpose engineering, construction, and metal fabrication (including stainless steel, cast iron, and aluminum).
• Manufacturing: Often fully ground (HSSG), which provides superior dimensional accuracy and cutting geometry compared to rolled bits.
• Types: Available in various series, most commonly the Jobber series (standard length). 

Common Specifications:

• Diameters: Ranging from very small fractional/metric sizes up to around 13mm-16mm,, with larger, reduced-shank versions also available.
• Finish: Common finishes include bright, black oxide, or titanium coating for increased heat resistance and longevity.

Product Details:

 “straight shank” describes the type of shank and “twist” refers to the cutting portion of the bit. There are also “keyed shanks”, “tapered shanks”, and others. There are both “straight drills”, like used on rock & concrete as well as “blade drills” commonly used on wood.
