Description
The JK Super Drive HSS 3.18 mm (1/8 inch) Jobber Rolled Forged Drill is designed to drill a variety of materials with great precision and performance. These 3.18 mm diameter, 65 mm long, high-speed steel (HSS) drills work well with mild steel, EN-9, cast iron, castings, plastics, wood, and stainless steel. The chrome coating offers excellent wear resistance and corrosion protection, while the rolled forged construction and shank design improve structural integrity and torsional strength. With 118° and 135° point angles for flexible cutting, this 10-piece set produces reliable, tidy holes for auto shops, factories, workshops, and do-it-yourself projects. The sturdy HSS construction, which falls within the 2.70–13.0 mm diameter range, keeps its edge under trying circumstances for effective penetration and longer tool life.
Features
:- For heavy-duty drilling, rolled forged HSS structure offers remarkable fatigue resistance and torsional strength.
- The chrome finish guarantees smoother chip evacuation for cleaner holes, lowers friction, and prevents corrosion.
- For general applications, the jobber length (65 mm overall, 36 mm flute) maximizes reach, stiffness, and chip removal.
- Dual point angles (118°/135°) offer a range of applications, from durable stainless steel to soft plastics and wood.
- Under extreme heat and frequent use, high-speed steel keeps its edge.
- For workshops that frequently require precise drilling, the 10-pack provides bulk convenience.
Applications
:- EN-9, stainless steel, and mild steel precision hole drilling for fabrication and automotive applications.
- Make clean holes in cast iron and castings for production and maintenance.
- General drilling for woodworking and do-it-yourself projects using plastics, wood, and composites.
- Reliable rolled forged performance is necessary for workshop assembly and maintenance.
Usage
:- Choose the right RPM and speed for the material and secure the rolled shank in a normal drill chuck.
- Utilize the low friction characteristics of chrome finishes by applying consistent pressure with metal lubricant.
- To maximize cutting efficiency, choose a point of 118° for common materials and 135° for harder steels.
- In deeper holes, use peck drilling with a 36 mm flute for efficient chip clearance.
- To maintain the integrity of the rolled forging and the sharpness of HSS, clean and store under protection after use.
