Review STARRETT Starret 86mm 3-3/8 Inch Deep Cut Hole Saw Extra Cobalt Bi metal New

The **Starrett DCH0434-G (86mm / 3-3/8") and DCH0338-G (Bi-Metal) Hole Saw Set** represents a premium solution for professionals and DIY enthusiasts who demand precision, durability, and versatility in their cutting tasks. Engineered by Starrett, a brand synonymous with quality and innovation in measurement and cutting tools, these hole saws are designed to deliver clean, accurate cuts through a wide range of materials, including wood, plastic, drywall, and even thin metal. The **86mm (3-3/8") DCH0434-G** is a high-performance, high-speed steel (HSS) hole saw that excels in applications requiring speed and efficiency, such as installing pipes, electrical conduits, or mounting fixtures where a slightly larger diameter is necessary. Its robust construction ensures minimal deflection during use, while the sharp, hardened teeth maintain their cutting edge longer than standard hole saws, reducing downtime and increasing productivity. The **DCH0338-G Bi-Metal hole saw**, on the other hand, is a game-changer for tougher materials like stainless steel, aluminum, and hardened plastics. The bi-metal construction combining a high-speed steel cutting edge with a tougher alloy body provides superior wear resistance and heat dissipation, allowing it to cut through abrasive materials without premature dulling or warping. This makes the DCH0338-G ideal for industrial applications, automotive work, or any project where durability and longevity are critical. Both hole saws feature a **smooth, precision-ground shank** that fits snugly into most drill chucks, ensuring stability and reducing vibration during operation. The **DCH0434-G** is particularly well-suited for general-purpose drilling, where a balance of speed and accuracy is required, while the **DCH0338-G** stands out for its ability to tackle demanding materials without sacrificing performance. Together, these two hole saws form a versatile duo that caters to both everyday and specialized cutting needs, making them an indispensable addition to any toolkit. Whether you're a contractor, a woodworker, or a hobbyist, the Starrett DCH0434-G and DCH0338-G offer the reliability and precision needed to achieve professional results with every cut.

### **Pros and Cons of buying a Starrett DCH0434-G (Starrett 86mm 3-3/8" Hole Saw, Bi-Metal)**

1. **High-Quality Bi-Metal Construction** The bi-metal design combines high-speed steel with carbon steel, offering superior durability and heat resistance compared to standard carbon steel or HSS-only saws. This makes it better suited for cutting through tough materials like metal, plastic, and some composites without overheating or warping.

2. **Precision and Accuracy** Starrett is a well-known brand in precision cutting tools, and this hole saw is designed for clean, square cuts. The sharpness and alignment help reduce tear-out and ensure consistent hole sizes, which is critical for applications requiring tight tolerances.

3. **Versatility** The 86mm (3-3/8") size is a common diameter for general-purpose hole cutting, making it useful for plumbing, electrical work, HVAC installations, and woodworking. It can handle a variety of materials, including soft metals (e.g., aluminum, copper), wood, and some plastics.

4. **Durability** The robust construction means it can withstand repeated use without losing sharpness quickly. The bi-metal edge resists wear better than single-metal saws, extending the tool s lifespan.

5. **Compatibility with Standard Drills** Like most hole saws, this one fits standard drill chucks (1/2" or 3/8" depending on the drill), making it easy to use with most power tools. The shank is designed for reliable grip.

6. **Good for DIY and Professional Use** Whether you're a homeowner tackling a repair job or a professional contractor, this hole saw strikes a balance between affordability and performance. It s not an industrial-grade tool, but it s reliable for everyday tasks.

7. **Ease of Replacement** Bi-metal hole saws are generally easier to sharpen or replace than carbide-tipped ones, which can be more expensive and require specialized tools.

---

1. **Not Ideal for Very Hard Metals** While bi-metal is better than standard carbon steel, it may struggle with extremely hard materials like stainless steel, cast iron, or high-strength alloys. For these, a carbide-tipped hole saw or a specialized metal-cutting bit would be more appropriate.

2. **Requires Proper Cooling** Like all hole saws, this one generates heat during use. Frequent stops to let it cool (or using a lubricant like cutting oil) may be necessary when cutting through tough materials to prevent burning or warping the saw.

3. **Limited Depth Capacity** The depth of cut is typically limited by the length of the saw s teeth and the drill s power. For deep holes (e.g., in thick metal or wood), you may need to make multiple passes or use a longer hole saw.

4. **Potential for Clogging** When cutting wood or composite materials, sawdust can clog the teeth, reducing efficiency. Regular cleaning or using a hole saw guard can help mitigate this.

5. **Price Relative to Alternatives** While not excessively expensive, bi-metal hole saws are generally more costly than basic carbon steel ones. If you re only cutting soft materials (e.g., wood or plastic), a cheaper option might suffice.

6. **Shank Size Compatibility** Ensure your drill has the correct chuck size (usually 1/2" for this saw). Using a drill with an incompatible chuck can lead to slippage or damage.

7. **Not as Long-Lasting as Carbide-Tipped Saws** For heavy-duty or frequent use, carbide-tipped hole saws (e.g., from brands like Freud or Onsruz) may last longer, though they are more expensive upfront.

The **Starrett DCH0434-G (86mm bi-metal hole saw)** is a solid, mid-range tool that excels in versatility and durability for general-purpose hole cutting. It s a great choice for DIYers, handymen, and professionals who need a reliable saw for soft metals, wood, and plastics without investing in a premium carbide-tipped option. The bi-metal construction ensures better longevity than standard saws, and Starrett s reputation for quality adds to its appeal.

However, if your primary use involves cutting **hard metals, stainless steel, or extremely thick materials**, you may find it less efficient than a carbide-tipped saw. Additionally, users should be mindful of cooling and proper technique to maximize performance.

- **Buy it if:** You need a **durable, all-purpose hole saw** for wood, soft metals, or general construction work and want a balance between cost and performance. It s a good long-term investment for occasional to moderate use.

- **Consider alternatives if:** You frequently cut **hard metals or require extreme precision/depth**. In those cases, a **carbide-tipped hole saw** (e.g., Freud or Onsruz) or a **specialized metal-cutting bit** would be more suitable.

- **Pair it with:** A **hole saw guard** (to reduce tear-out), **cutting oil/lubricant** (for metal cutting), and a **quality drill** (e.g., DeWalt or Makita) to ensure optimal performance.

For most homeowners and general contractors, the **Starrett DCH0434-G is a well-rounded, reliable choice**. If budget allows, consider buying a **carbide-tipped saw** for hard metals as a complementary tool.
