5-Piece Extra-Long HSS Twist Drill Bit Set

Shallow drill reaches, limited clearance in tight spaces, and snapped bits shouldn't stop you from completing deep-hole drilling projects. Reach difficult angles and bore straight, deep holes effortlessly with our 5-piece extra-long High-Speed Steel (HSS) drill bit set, engineered with an extended 5.9 in length for extended-reach drilling.

Crafted from premium High-Speed Steel with precision-ground twist flutes, these 5.9 in long bits deliver superior heat resistance, sharp cutting edges, and rapid chip evacuation. The 5-piece assortment includes essential drill bit diameters to give you the perfect size selection for drilling through wood, plastics, acrylics, aluminum, and light metals. Designed with standard straight shanks, this set fits securely into handheld electric drills, cordless drivers, and drill presses for accurate, wobble-free deep boring.

Key Features

• Extended 5.9 in Length: Provides extra reach to bore deep holes, clear recessed channels, and drill through thick materials or tight frame gaps.

• 5-Piece Essential Size Selection: Includes five versatile bit sizes for precision drilling and accurate pilot holes.

• High-Speed Steel (HSS) Build: Heat-treated alloy steel retains sharp cutting edges under high rotational friction and thermal expansion.

• Rapid Spiral Chip Evacuation: Deep twist flute design pulls wood chips, plastic shavings, and metal filings out quickly to prevent clogging and binding.

• Broad Material Compatibility: Bores cleanly through softwood, hardwood, plywood, PVC pipes, plastics, acrylic, aluminum sheets, and thin metal plates.

• Universal Straight Shank: Fits standard keyless and keyed drill chucks on cordless drills, impact drivers, and benchtop drill presses.

Why Choose Our Extra-Long HSS Drill Bit Set Unlike standard-length drill bits that stop short or extension adapters that wobble and lose centering, our 5.9 in continuous HSS drill bits provide a rigid, unified shaft. They ensure straight, true holes even at maximum extension depth.

Perfect For
