HSS-G wood drill bit set FAMAG 1594.8 in plastic case

HSS-G wood drill bit set FAMAG 1594.8 uses high-speed steel alloy, fully ground along the entire flute. This process preserves the steel's crystalline structure, resulting in excellent wear resistance during continuous use. Spiral flutes efficiently remove chips, reducing friction and heat. The round shank fits standard chucks and operates smoothly at 2400–8000 RPM.

Each bit drills precise, clean holes in hardwood, laminated board, polycarbonate, acrylic, PVC, and fiber-reinforced composites. The plastic case keeps bits organized and protects cutting edges during transport.

Construction and Material of the HSS-G Wood Drill Bit Set

HSS-G Alloy Steel

Bits are made from high-speed steel alloy. Fully ground flutes maintain the internal grain structure, providing greater hardness and edge retention than rolled or twisted flutes. The steel composition supports extended cutting without premature dulling.

• Material: HSS-G high-speed steel alloy
• Manufacturing: fully ground flutes
• Crystal structure: preserved during grinding
• Edge retention: extended through controlled heat treatment

The ground flute profile creates a polished channel for smooth chip evacuation and effective heat dissipation, protecting both bit and workpiece.

Spiral Flute Design

Helical flutes wrap around the bit, pulling chips upward and out as the bit rotates. The open channel handles high chip volumes without clogging. Reduced friction means cooler operation and longer intervals between sharpening.

• Flute profile: helical spiral
• Chip evacuation: rapid, continuous
• Friction coefficient: low
• Heat generation: minimized

The spiral angle is optimized for wood and soft plastics. Sharp cutting edges stay clean, improving hole finish and accuracy.

Round Shank Configuration

Each bit has a cylindrical shank for secure seating in three-jaw chucks. The round profile distributes clamping force evenly, preventing slippage at high speeds. Shank diameter is consistent across the set for easy bit changes.

• Shank type: round, cylindrical
• Chuck compatibility: standard three-jaw
• Clamping stability: even force distribution
• Speed range: 2400–8000 RPM

The shank length provides sufficient grip for portable drills and drill presses. Concentricity ensures true running without wobble.

Performance Characteristics

Operating Speed Range

The set is rated for 2400–8000 RPM. Smaller diameters run at higher speeds, larger bits slower to maintain optimal cutting velocity. HSS-G material resists heat at these speeds without losing temper.

• Minimum speed: 2400 RPM
• Maximum speed: 8000 RPM
• Speed selection: varies by bit diameter
• Thermal stability: maintained across speed range

Higher speeds yield smoother holes in hardwood and dense plastics. Ground flutes and low-friction design prevent overheating during extended use.

Surface Finish and Accuracy

Drilled holes are smooth and clean with minimal tear-out. Sharp edges cut fibers cleanly, and dimensional accuracy is consistent as the bit resists deflection. Polished flutes leave a fine interior finish.

• Hole finish: smooth, minimal tear-out
• Dimensional accuracy: consistent across depth
• Edge geometry: sharp, precise
• Deflection: minimal under normal load

Material hardness and flute design deliver professional results in softwood, hardwood, acrylic, and polycarbonate, with no stress cracks or chipping.

Compatible Materials

Wood and Engineered Wood Products

Bits cut cleanly through hardwood, softwood, plywood, MDF, particleboard, and laminated panels. Spiral flutes handle fibrous chips without clogging. Sharp edges minimize splintering at entry and exit.

• Hardwood: oak, maple, beech, ash
• Softwood: pine, spruce, fir
• Engineered panels: plywood, MDF, particleboard
• Laminated boards: melamine-faced chipboard

Drilling speed and feed rate can be adjusted for wood density. HSS-G steel maintains its edge even in abrasive materials like MDF.

Plastics and Composites

Polycarbonate, acrylic, PVC, and fiber-reinforced composites are drilled cleanly without melting or cracking. Low-friction flutes prevent heat buildup, and sharp edges produce smooth holes in brittle materials like acrylic.

• Polycarbonate sheet: impact-resistant glazing
• Acrylic (PMMA): display panels, signage
• PVC: pipe, sheet, profile
• GFRP: glass fiber-reinforced plastic
• HPL: high-pressure laminate
• Trespa: weather-resistant composite panel

Composite materials with glass or carbon fiber benefit from HSS-G steel's hardness. Bits resist abrasive wear and maintain hole quality over multiple uses.

Common Applications

Carpenters and joiners use the set for furniture, cabinetry, and trim. Electricians drill cable pass-throughs in wood and plastic. Sign makers bore mounting holes in acrylic and composites. Model makers and hobbyists use it for precision work. Maintenance technicians keep the set for general drilling in workshops and on-site. The diameter range covers most fastener and dowel sizes.

Packaging and Storage

Plastic Case

The set comes in a molded plastic case with individual compartments for each bit, protecting edges from impact and moisture. A snap-lock lid secures the bits. The compact case fits toolboxes and service vehicles.

• Case material: rigid plastic
• Compartments: individual slots per bit
• Lid closure: snap-lock
• Protection: impact and moisture resistance

Clear or labeled compartments simplify selection and inventory checks, preventing loss of bits.

Technical Reference

The FAMAG 1594.8 series includes three configurations. Model 1594.835 contains five bits: Ø3, 4, 5, 6, and 8 mm. Model 1594.845 also holds five bits: Ø4, 5, 6, 8, and 10 mm. Model 1594.838 offers eight bits: Ø3, 4, 5, 6, 7, 8, 9, and 10 mm. All variants use HSS-G material, ground flute construction, and round shank design. Speed recommendations scale with diameter: smaller bits run faster, larger bits slower, within the 2400–8000 RPM range.
