Description
The JK Super Drive HSS 3.18 mm (1/8 inch) Jobber Straight Shank Drill offers accurate and dependable performance when drilling stainless steel, mild steel, EN-9, cast iron, castings, plastics, and wood. These 75 mm overall length bits are made of chrome-finished high-speed steel (HSS) and have dual 118° and 135° point angles for flexible material cutting. The 43 mm flutes provide effective chip removal for clean holes, and the straight shank firmly fits conventional chucks. This set of ten provides stability and heat-resistant durability for professional workshops and do-it-yourself projects, making it ideal for auto shops and manufacturing facilities.
Features
:- High hardness and wear resistance are guaranteed by HSS material, which keeps its sharp edges over extended high-heat drilling.
- For cleaner results, the chrome finish reduces friction, prevents corrosion, and facilitates smoother chip evacuation.
- From soft plastics to durable stainless steel, dual point angles (118° for ordinary use, 135° for tougher metals) provide versatility.
- Standard drill chucks with a straight shank offer vibration-free grip for precise, steady operation.
- For efficient general-purpose hole-making, the jobber length (75 mm overall, 43 mm flute) strikes a compromise between stiffness and reach.
- The ten-piece set offers constant quality and long tool life for professional use in large quantities.
Applications
:- Precise hole drilling in stainless steel and mild steel for fabrication and vehicle maintenance.
- Hole creation in cast iron, EN-9, castings for manufacturing fixtures and components.
- Adaptable drilling for general repairs, woodworking, prototyping, and plastics.
- Work in the workshop requires accurate sizing for a variety of materials.
Usage
:- Fit a straight shank into the drill chuck and adjust the speed according to the material (low for steel, high for wood and plastic).
- To regulate heat and prolong the sharpness of the HSS edge, lubricate metals.
- To increase penetration, use an angle of 118° for softer materials and 135° for steels.
- For 43 mm of flute chip clearance, drill with constant pressure while occasionally drawing back.
- To preserve performance and preserve the chrome finish, clean and store dry after use.
