Milescraft 1312 Drill Block
The Milescraft 1312 Drill Block is a handheld drilling guide that provides six imperial drill sizes (1/8″, 3/16″, 1/4″, 5/16″, 3/8″, 1/2″). Its hardened steel guides support precise alignment, while built-in vertical and horizontal centerlines help ensure accuracy on both axes. Non-slip feet grip the work surface to prevent movement and surface marring, making it suitable for finish work and fragile materials. This compact jig is designed for quick setup and repeatable results on straightforward drilling tasks.
The Original V-DrillGuide STD1000DGNP
The V-DrillGuide STD1000DGNP offers a broad range of drill sizes from 1/8″ to 3/8″ with precise 1/64″ increments. It is designed for use on flat surfaces, round parts, and corners, making it versatile for furniture, cabinetry, and general construction. The drill guide is constructed from special nickel alloyed steel and heat-treated for durability, providing long-lasting accuracy for demanding projects where alignment matters most.
HIPULX Drill Block Guide
The HIPULX Drill Block Guide emphasizes precision and portability. It features built-in vertical and horizontal center lines for accurate alignment, plus a V-groove design suitable for flat surfaces, corners, and round pipes. The ABS body with a durable drill sleeve core, alongside non-slip feet and rubber pads, ensures stability during drilling. At a compact weight and size, it is easy to carry for fieldwork or small shop setups and supports consistent straight drilling across a variety of tasks.
BullseyeBore Core CR1-100
BullseyeBore Core CR1-100 uses a red laser alignment system to project circular patterns that show when your drill is properly perpendicular to the work surface. This enables drilling straight holes with minimized guesswork, especially on vertical walls or ceilings. The model supports standard bits from 2″ to 5″ and offers extended battery life compared to green laser variants, making it well-suited for indoor workshops and detailed alignment tasks where precision is essential.
Kreg KMA3225 Shelf-Pin Jig
The Kreg Shelf-Pin Jig provides six holes at 1-1/4 inch increments and uses a 32 mm system to precisely place shelf pin holes for hinges and drawer slides. Hardened-steel drill guides support clean, straight holes, contributing to wobble-free shelving and reliable hardware alignment. This jig is ideal for cabinetmaking and floating shelf installations where uniformity across multiple joints matters.
Buying Guide
- Intended use: Choose a guide that matches your typical workpieces—flat surfaces, corners, or round stock—and whether you need angled drilling support.
- Hole size range and increments: Look for guides offering the sizes you use most often and the granularity that suits your projects (e.g., 1/64″ increments vs standard steps).
- Material and durability: Steel or nickel-alloy steel guides withstand wear and provide repeatable accuracy; ABS bodies are lighter but may be less durable for heavy-duty use.
- Alignment features: Built-in centerlines, V-grooves, and laser alignment help reduce drift and misalignment, especially on DIY setups.
- Stability: Non-slip feet or rubber pads prevent slides and marring; portability may be important for field work or tight shop spaces.
- Versatility: Some guides handle multiple drill bits and surfaces (flat, round, corners), while others specialize in shelving or corner applications.
- Ease of use: Consider guides with simple adjustments and minimal setup time to maximize productivity on quick-turn projects.
- Compatibility: Ensure the guide can be used with your existing drill chucks (e.g., 3/8″ chuck) and that it accommodates your typical bit sizes.
