Compact Design for Confined Work Areas
Specially engineered for use in tight or awkward spaces, this step drill bit features a shorter, tapered profile that fits easily into electrical boxes, cabinets, and narrow panels-perfect for compact handheld tools and cordless drills.
Smooth, Burr-Free Hole Transitions
Precision-ground HSS cutting edges and stepped geometry deliver clean, concentric holes with minimal burring. The dual-flute spiral design allows quick chip removal and helps reduce heat buildup for smoother drilling, even on layered or thin materials.
Durable High-Speed Steel Construction
Constructed from heat-treated industrial-grade HSS, this bit resists wear, dulling, and chipping-offering excellent performance and a long service life even under repetitive use and high speeds.
Versatile for Multi-Diameter Drilling
This all-in-one tool allows for multiple hole sizes without changing bits. Ideal for professionals and DIY users alike working on junction boxes, electrical enclosures, custom panels, or furniture modifications in tight spots.
Compact HSS Body for Tight Access
Made from high-speed steel (HSS), this short-length step drill bit is designed for use in confined areas such as control panels, electrical boxes, and machine enclosures. Its compact size allows for easy maneuvering where full-length bits can't reach.
Multi-Diameter Hole Cutting in One Tool
Featuring a tapered step profile, this bit allows for drilling various hole sizes without changing tools. Ideal for quick adjustments in space-restricted environments, such as switchboards or cabinet frames.
Fast, Burr-Free Results with Spiral Flute Design
A polished spiral flute helps evacuate chips quickly and reduces friction, enabling smoother, cleaner drilling through sheet metal, plastic, or laminate-even in awkward positions.
Corrosion-Resistant Surface for Jobsite Durability
The drill bit is finished with a rust-resistant coating that protects it from moisture and debris, extending service life in garages, maintenance rooms, or outdoor job settings.
Low-Vibration and Easy Handling
Lightweight and center-balanced for stable control in tight spots, it delivers reduced vibration and excellent handling-whether used with cordless drills or compact benchtop presses.
Compact Design for Confined Area Access
Engineered with a shorter body and reduced overall length, this step drill bit is perfect for use in tight, hard-to-reach areas such as electrical cabinets, control boxes, and mechanical enclosures. It enables clean, efficient drilling even when space is limited.
High-Speed Steel for Long-Lasting Performance
Made from industrial-grade high-speed steel (HSS), this bit offers superior wear resistance, thermal stability, and sharpness retention. It stays effective during continuous, high-speed drilling-ideal for repetitive work in metal, plastic, or wood where bit access is constrained.
Multi-Diameter Cutting in One Compact Tool
The pagoda-style stepped profile enables multiple hole sizes with one compact bit-saving time and tool changes. Each step is precisely machined to ensure clean transitions and accurate hole diameters, even in small or awkward working areas.
Smooth, Vibration-Free Drilling
Designed for stability and control, this drill bit delivers minimal vibration and clean hole finishes. It's ideal for technicians, electricians, and DIYers working in confined spaces where precision and efficiency matter.
This compact step drill bit features a short-body pagoda design with CNC-machined concentric steps, ideal for drilling in restricted or hard-to-reach spaces such as control panels, electrical enclosures, and narrow cavities. The smooth transitions between steps ensure burr-free, clean holes even in tight working conditions.
Built from premium high-speed steel (HSS) and heat-treated for maximum durability, this bit delivers exceptional resistance to heat, wear, and impact. It maintains sharpness during frequent use, making it suitable for metal sheets, plastic panels, PVC, and composite materials.
The polished spiral flute structure allows efficient chip removal, minimizes clogging, and reduces friction and heat buildup-especially important when working in enclosed or poorly ventilated areas. This design improves tool longevity and drilling precision.
Refined through vacuum-degassed steel processes, the bit offers excellent toughness and edge retention. It remains stable even under frequent on-site drilling in confined setups.
Advanced quenching and tempering techniques give the bit a reliable balance between strength and ductility-preventing cracking or deformation during handheld use in awkward angles.
The shortened length and tapered steps enable drilling multiple hole sizes in a single pass with limited clearance-reducing bit change time and allowing fast hole adjustments in small compartments.

Q1: What makes this compact step drill bit different from regular twist or standard step drill bits?
A: This compact step drill bit is specifically designed for tight and narrow spaces where standard bits may be too long or bulky. Unlike twist bits or longer step bits, its short and tapered pagoda-style body allows for efficient multi-size drilling in confined areas-such as electrical boxes, tight panels, or cabinet interiors-while still delivering clean, burr-free holes.
Q2: What materials is this bit suitable for in tight-space applications?
A: It works exceptionally well on thin and layered materials commonly found in constrained workspaces, including sheet metal (aluminum, stainless steel), plastics (PVC, acrylic), laminates, and thin wood panels. Ideal for electricians, HVAC technicians, and DIY users dealing with space-restricted installations.
Q3: Are compact size and custom options available?
A: Yes. This bit is available in compact step ranges like 4-12mm and 4-20mm, with short overall lengths for space efficiency. Options for custom step spacing, flute design, coatings (e.g., TiN, TiCN), and shank types (hex or round) are available to meet specific professional or toolkit requirements.
Q4: Can this be used with portable or handheld tools in tight locations?
A: Definitely. Its short length and balanced design make it ideal for use with cordless drills and compact handheld electric drills. The bit's durable HSS construction ensures reliable performance, reduced vibration, and smooth operation even in awkward or limited-access angles.
