Description
Superior strength and precision are offered by the JK Super Drive HSS 3.97 mm (5/32 inch) Jobber Rolled Forged Drill for drilling in mild steel, EN-9, cast iron, castings, plastics, wood, and stainless steel. These 75 mm overall length drills with 118° and 135° point angles for adaptable performance are made by rolled forging high-speed steel (HSS) with a chrome finish. The 43 mm flute guarantees effective chip evacuation, while the rolled shank improves torsional strength and fatigue resistance. This set of ten sturdy, heat-resistant tools is perfect for both professional and do-it-yourself drilling jobs in the 2.70 to 13.0 mm diameter range, and it is made for auto shops and manufacturing facilities.
Features
:- For outstanding torsional strength and a longer lifespan under heavy loads, rolled forged HSS construction increases grain flow and density.
- For cleaner, more effective holes, a chrome finish lowers friction, inhibits corrosion, and facilitates easier chip removal.
- The smooth transition from soft plastics to hard stainless steel is made possible by the dual point angles (118° for ordinary materials and 135° for tougher steels).
- Compared to conventional straight shanks, rolled shanks are more stiff and less likely to break under high-torque conditions.
- For medium-depth precision drilling, the ideal jobber length (75 mm overall, 43 mm flute) offers the best reach, stiffness, and flute capacity.
- Bulk reliability for workshops is provided by the pack of ten, guaranteeing steady performance in repetitive industrial applications.
Applications
:- High-precision hole drilling in stainless and mild steel for the production and assembly of automotive parts.
- Strong drilling in castings, EN-9, and cast iron for the production of fixtures, jigs, and equipment parts.
- Adaptable hole-making for woodworking, repair, and prototyping in composites, plastics, and wood.
- Duties involving production lines and industrial maintenance that call for robust rolled forged performance.
Usage
:- Securely insert the rolled shank into the drill chuck, then choose the RPM according to the material (higher for plastics, lower for steels).
- To reduce heat and increase HSS edge retention while in use, lubricate metals with cutting lubricant.
- For mild steel, wood, and plastics, use a 118° point; for cast iron and stainless steel, use a 135° point.
- To use the 43 mm flute for efficient chip clearance and prevent binding, apply constant pressure.
- To maintain the integrity of the rolled forging and the chrome surface, check for wear after sessions and keep under protection.
