230 Pieces Titanium Twist Drill Bit Set: Hands-On Review

Huge size range, clean cuts, and a sturdy case make this set a smart buy.

We’ve all been there—mid-project with the wrong bit size or a dull tip that burns wood and skates on metal. I wanted one kit that covers tiny pilot holes up to 1/2-inch clean bores, without hunting through random boxes. This 230-piece titanium twist drill set promised fast starts, smooth drilling in wood, plastic, aluminum, and cast iron, plus a hard case to keep it all sorted. I put it to work on a weekend build and a few metal fixes to see if it’s worth your money.

Is 230 Pieces Titanium Twist Drill Bit Set Good?

My verdict: yes—for DIYers and pros who want a full spread of sizes, fast starts, and tidy storage. If you drill wood, plastic, aluminum alloy, or cast iron, this is a strong all-in-one kit. For hardened steel, you’ll want cobalt, but for most shop and home tasks, this set punches above its price.

In my shop, I used the 1/8-inch bit to pre-drill poplar for cabinet pulls. The 135° split point bit didn’t wander and kept holes clean. Later, I used a 3/8-inch bit on a cast iron bracket at low speed with cutting oil. The cut was smooth, and the tip stayed sharp. The hard case kept everything in place, so I didn’t waste time hunting sizes.

My First Impression

The set arrived well-packed in a hard storage case. The labeling inside was clear, and sizes ran from tiny 3/64-inch up to 1/2-inch. The titanium-coated high-speed steel looked even, with clean flutes and sharp 135° split points.

Setup was simple: pick the size, chuck it, and drill. On pine and MDF, the bits grabbed quickly with minimal tear-out. On aluminum angle stock, the bit started true without a center punch. My first reaction was relief—no skating, less heat, and no mystery sizes rolling around the bench. It felt like going from a junk drawer to a proper toolkit.

What Makes It Stand Out / Key Features

• 230-piece size range from 3/64″ to 1/2″ for broad project coverage
• 135° split point for quick starts with less walking on metal and plastic
• Titanium-coated high-speed steel for better wear resistance and cooler cuts
• Hard storage case with labeled slots for fast size selection
• Ideal for wood, cast iron, aluminum alloy, plastic, and fiberglass
• Balanced flute design for smoother chip removal and cleaner holes

What I Like

• Huge size coverage means fewer runs to the store
• Fast starts with the 135° tip save time and improve accuracy
• Titanium coating holds up well on wood, plastic, and soft metals
• The case keeps bits organized and easy to grab mid-project
• Clean holes with less tear-out in softwood and MDF
• Good value compared to buying individual sizes

What Could Be Better

• Not ideal for hardened steel; use cobalt for that
• Some small bits can snap if pushed too hard—use light pressure
• The case hinges could be stronger for jobsite abuse
• Bits may need occasional touch-up sharpening with heavy use
• No step bits included; you’ll need a separate set for sheet metal

My Recommendation

If you want one kit for home builds, shop tasks, furniture installs, and light metal work, the 230 Pieces Titanium Twist Drill Bit Set is a great fit. It’s best for makers who value speed, clean holes, and organized storage. It is also ideal for anyone upgrading from a small, mismatched bit pile. If you drill hardened steel daily, pair this with a cobalt set. For everything else, the value and range here are hard to beat.

Best for	Why
DIY furniture and cabinetry	Clean starts and minimal tear-out in wood and MDF
Light metalwork (aluminum, cast iron)	135° tip reduces walking; titanium helps with wear
General shop and home repairs	Huge size range plus a hard case for quick access

Alternative Products You Can Consider

DEWALT Titanium Drill Bit Set (21-Piece) — A tighter, pro-grade set with common sizes and a durable case. Best if you want fewer bits but higher-end build and brand support. It won’t match the 230-piece coverage, but the core sizes are excellent for everyday use.

COMOWARE Cobalt Drill Bit Set (29-Piece) — Better for hardened steel and stainless. It has fewer sizes, but the M35 cobalt material handles tough metals that titanium-coated HSS should avoid. If you work metal often, this could pair well with the 230-piece kit.

IRWIN High-Speed Steel Jobber Length Set (29-Piece) — Reliable jobsite performance with precise sizing. Not as broad as 230 pieces, but the quality and consistency are strong. Best for users who want a mid-size set with dependable results.

Product	Best For	Key Difference
230 Pieces Titanium Twist Drill Bit Set	All-around DIY and shop use	Massive size range, titanium-coated HSS, hard case
DEWALT Titanium Drill Bit Set (21-Piece)	Everyday drilling with core sizes	Fewer bits, premium build, strong brand support
COMOWARE Cobalt Drill Bit Set (29-Piece)	Hardened steel and stainless	Cobalt material for tough metals, smaller size range

Final Verdict: Which Should You Buy?

If you want one kit to cover most drilling jobs in wood, plastic, aluminum, and cast iron, the 230 Pieces Titanium Twist Drill Bit Set is the easy choice. It gives you fast starts, clean holes, and a huge range of sizes in a tidy case. For hardened steel, add a cobalt set.

Pick the DEWALT 21-piece if you value fewer, high-usage sizes with premium feel. Choose the COMOWARE cobalt set if you mostly drill tough metals. The IRWIN HSS set is a solid middle ground for reliable jobsite work. For most homeowners and makers, though, the 230-piece kit offers the best mix of coverage and value.

FAQs Of 230 Pieces Titanium Twist Drill Bit Set

Can these bits drill stainless steel?

They can handle light stainless at low speed with oil, but for frequent stainless or hardened steel, use cobalt bits.

Do the bits walk on metal?

The 135° split point helps prevent walking. For critical holes, use a center punch and slow speed.

Will the titanium coating wear off?

All coatings wear over time, but with proper speed and lubrication, these hold up well for wood, plastic, and soft metals.

Is the case durable?

The case is hard and organized. It’s good for shop use; avoid rough drops to keep hinges and latches intact.

Do I need cutting oil?

For metal, yes—use cutting oil and slow speed. For wood and plastic, you can drill dry at appropriate speeds.
