Best Drill Bits With Step Tips for Metal, Wood, and Plastic
Drill bits with step tips are designed to start holes with less walking than conventional twist bits, and some sets also help enlarge existing holes. The Pro Edge set is best for mixed-material projects, while Crosstar and Drill America offer cobalt options for harder metals. EZARC is a single step bit for larger holes, and the size-marked stepped-point set is a straightforward option for general drilling. Compare bit style, material, size range, and shank before choosing.

| Crosstar 21-Piece Cobalt Set | Hard-metal drilling | M35 cobalt bits and TiAlN coating |
| Drill America 29-Piece Set | Size selection for varied holes | 29 jobber-length bits |
| EZARC Step Drill Bit | Enlarging holes to larger diameters | One bit with nine steps |
| Stepped Point Drill Bit Set | Basic precision drilling | 135-degree split point and storage tube |
Pro Edge 14-Piece Stepped Point Drill Bit Set
Best for: DIYers who need a range of stepped-point bits for different materials. This set spans 1/16 to 1/2 inch and is listed for metal, wood, plastic, and acrylic. Its stepped point is designed to center quickly and reduce walking, while the listing says it can help limit blowout in delicate plastics.
The bits are described as M2 high-speed steel with a titanium coating. A three-flat shank is intended to resist slipping in the chuck, and the set includes a storage case. Choose it if you want a multi-bit set rather than one large-diameter step bit. The listing does not specify individual bit sizes, so check the size layout if exact increments matter.
Crosstar 21-Piece M35 Cobalt Set
Best for: Buyers prioritizing hard-metal work. Crosstar lists M35 cobalt steel with a 5% cobalt core and targets the bits at stainless steel, high-temperature alloy steel, and bearing steel. The 135-degree split-point step design is intended to start without pre-drilling and can be used to enlarge existing holes.
A TiAlN coating and three-flat shank are also listed, along with an indexed storage case. This set is a better fit for metal-focused work than buyers seeking a broad wood-and-plastic kit. The listing’s hardness and performance figures are manufacturer claims; material choice alone does not guarantee results, so use appropriate speed, pressure, and cutting practice.
Drill America 29-Piece Cobalt Set
Best for: Users who want many fractional sizes for new holes or enlarging existing ones. The set covers 1/16 to 1/2 inch in 64ths and includes a round storage case. Drill America lists acrylic, steel, brass, and other hardened metals among its intended materials.
The bits have a 135-degree split point, gold oxide finish, and jobber length. Most sizes have a three-flat shank to help prevent spinning, while sizes 11/64 inch and smaller have round shanks. That shank difference is worth checking if a consistent anti-slip profile across every bit is important. Choose this set for size variety rather than a single large step bit.
EZARC M35 Cobalt Step Drill Bit
Best for: Projects that need holes between 1/4 and 3/4 inch using one bit. Unlike sets of separate stepped-point twist bits, this is a single step drill with nine size increments. The listing identifies M35 cobalt steel, an AlTiN coating, a 1/4-inch hex shank, and a triple-flute design.
Its listed materials include metal, stainless steel, aluminum, and plastic. The triple flute is intended to improve stability, while the C-profile cutting edge is described as supporting smoother cutting. Choose it when the required diameter falls within its stated range. Avoid it if you need small pilot-size bits or a broad collection of separate bit diameters.
Stepped Point Drill Bit Set With Storage Tube
Best for: Buyers looking for a set centered on accurate starting and simple storage. The listed features include a 135-degree split point intended to reduce walking without center punching, an amber coating, a three-flat shank, and a size-marked storage tube.
The listing emphasizes cleaner holes and reduced burrs, but it does not provide the material composition or size range in the supplied product details. Confirm both before choosing it for a particular material or hole diameter. It may suit general drilling needs, but buyers focused on hard metals may prefer a product that explicitly specifies cobalt construction.
Buying Guide: How to Choose Drill Bits With Step Tips
Do you need stepped-point bits or a step drill bit?
Stepped-point sets contain separate bits, each with its own diameter and pointed tip. A step drill bit has several diameter steps on one bit and is commonly selected for enlarging holes within its stated range. Choose a multi-bit set for many smaller, distinct sizes; choose a single step bit when its stepped diameters match the holes you need.
Which bit material suits your work?
For harder metals, compare products that specify cobalt construction, such as the Crosstar and Drill America sets or the EZARC bit. For mixed-material tasks, the Pro Edge listing names metal, wood, plastic, and acrylic. Always check the product’s stated material range rather than assuming every bit is suitable for every material.
Why check the shank and size range?
A three-flat shank is intended to reduce slipping in a drill chuck. Some sets may use a different shank on smaller sizes, as Drill America specifies for bits 11/64 inch and below. Compare the exact diameter range and increments with the hole sizes required for your project. Also confirm whether the product is a set or a single bit.
Frequently Asked Questions
What does a stepped point do?
A stepped point is designed to start a hole more accurately and reduce bit walking compared with a conventional point. Product features may also describe smoother hole starts or reduced blowout for delicate materials.
Can stepped-point drill bits enlarge existing holes?
Yes. The Crosstar and Drill America listings describe their bits as suitable for enlarging existing holes. Check the selected bit’s size and material guidance before use.
Are cobalt bits better for metal?
Cobalt construction is a useful feature to compare for hard-metal applications. The Crosstar and Drill America sets specify cobalt, but the appropriate choice still depends on the material, hole size, and the bit’s listed guidance.
What is the difference between a set and a step drill bit?
A set provides multiple separate bits, generally with different diameters. A step drill bit has multiple diameter stages on one tool, such as the EZARC model’s nine listed steps.
