Best Split Tip Drill Bit Sets for Accurate Starts and Versatile Drilling
The best split tip drill bit set depends on the materials you drill, the hole sizes you need, and whether you want standard twist bits or side-cutting features. For general-purpose work, the DEWALT 14-piece set is best for a compact selection across wood, plastic, and metal; the 21-piece DEWALT set offers more sizes. The titanium-coated sets suit buyers seeking multiple size options, though split-point details differ between them.
| Product | Best For | Notable Feature |
|---|---|---|
| DEWALT 14-Piece DWA1184 | General-purpose drilling | 135-degree split point and three-flat shank |
| Titanium-Coated Serrated Set | Hole shaping and light-duty projects | 135-degree split point with side-cutting edges |
| DEWALT 21-Piece DWA1181 | More bit-size options | Black oxide coating and parabolic flutes |
| Eight-Piece Hex-Shank Set | Common metric sizes | Sizes from 3 to 10 mm |
| Two-Set Titanium-Coated Kit | Small workshop tasks | Six listed sizes from 3 to 8 mm |
DEWALT 14-Piece Split Point Drill Bit Set
This high-speed steel set is designed for drilling plastic, wood, and metal. Its 135-degree split-point tip helps reduce walking when starting a hole, while the tapered web is intended to improve durability and resist breakage. The three-flat shank is another distinguishing feature listed in the product name.
Best for: Homeowners and DIY users who want one compact set for several common materials. Choose this set if reducing bit movement at the start of drilling is a priority. It was selected for its explicit split-point design and stated material range.
Limitation: The set has 14 pieces, so buyers needing a broader selection of bit sizes may prefer the 21-piece option.
Titanium-Coated Serrated Split Point Set
This listing describes two sets of round-shank, high-speed steel bits in six sizes from 3 to 8 mm. The 135-degree split point is intended to help reduce wandering, and serrated side-cutting edges are designed to shape or enlarge holes after initial drilling. The product information names wood, plastic, aluminum, and thin sheet metal among its intended materials.
Best for: DIY users who want bits that can both drill and help widen or shape openings. The combination of a stated split point and serrated sides makes this a more specialized choice than a standard twist-bit set.
Limitation: The listed sizes are metric, and the side-cutting design may not be necessary for buyers who only need conventional drilled holes.
DEWALT 21-Piece Split Point Drill Bit Set
The DWA1181 is a 21-piece high-speed steel set with black and gold oxide coating. Its product title specifies a 135-degree split point and a 31-degree helix. The listed applications include general-purpose drilling in metal, hardwood, softwood, PVC, and fiberglass. A parabolic flute design is described as helping increase chip ejection in metal and wood.
Best for: Buyers who want more size choices than a smaller starter set and need bits for a range of listed materials. It was selected for its split-point specification, larger piece count, and broad application list.
Limitation: The supplied feature details say the coating helps resist corrosion and improve durability, but do not provide specific performance measurements.
Eight-Piece Titanium-Coated Hex-Shank Set
This set includes eight high-speed steel bits in metric sizes from 3 to 10 mm, including 6.5 mm. The listed features include a titanium coating, fully ground spiral flutes, and hexagonal shanks. The product information says the flute design is intended to reduce friction and heat, while the shank design is intended to prevent deflection.
Best for: Buyers looking for a broad spread of common metric sizes and a hex-shank format. This is a useful comparison option for wood, plastic, and metal projects, but the listing does not specify a 135-degree split point.
Limitation: Do not choose it specifically for split-point performance unless the seller confirms that feature; it is not stated in the supplied product details.
Six-Size Titanium-Coated Serrated Drill Bit Kit
This product listing describes two sets with six sizes from 3 to 8 mm, round shanks, high-speed steel construction, and titanium-coated surfaces. It also specifies a 135-degree split point and serrated side-cutting edges. The intended tasks include furniture assembly, woodworking, plastic fabrication, light metal projects, and DIY repairs.
Best for: Buyers comparing a compact metric range with a hole-shaping feature. The split point supports accurate starts, while the serrated edges are intended for enlarging or shaping openings.
Limitation: This is the same listing as the titanium-coated serrated set above, not a separate product. Check the listing’s size and package details before ordering to confirm which configuration is offered.
Buying Guide: How To Choose A Split Tip Drill Bit
What does a split point do?
A split-point tip is designed to start more accurately by helping reduce bit walking across a surface. It can be useful when placing a hole precisely, but it does not replace marking the location or securing the workpiece. The two DEWALT sets and the titanium serrated set explicitly list a 135-degree split point.
Which materials do you need to drill?
Match the bit material and stated applications to the work. The DEWALT 14-piece set lists plastic, wood, and metal. The 21-piece DEWALT set also lists PVC and fiberglass. For harder or specialized materials, confirm that the bit is designed for the job; none of these listings should be assumed suitable for every material.
Should you choose inch or metric sizes?
Check the measurements before buying. The titanium-coated sets list metric sizes, while the 14-piece DEWALT set’s supplied details do not specify its size range. Choose sizes that match your fasteners, project plans, or existing drill-bit collection.
Do shank and flute designs matter?
They can affect how a bit fits your drill and how it cuts. The DWA1184 has a three-flat shank, while the eight-piece set lists hexagonal shanks and the serrated kit lists round shanks. Review the product details and your drill’s chuck requirements before choosing. Flutes help carry material away; the DWA1181 specifically lists a parabolic flute design.
Frequently Asked Questions
Are split-point drill bits less likely to walk?
They are designed to help reduce walking when starting a hole. The amount of movement can also depend on the surface, bit condition, and how the workpiece is held.
Can split-tip bits drill wood and metal?
Some sets in this roundup list both wood and metal applications. Check each product’s stated materials and select a bit intended for the specific job.
Is a titanium coating the same as a split point?
No. A coating describes the bit’s surface, while a split point describes the cutting-tip geometry. A bit can have one feature without the other.
Are all the featured bits split point?
No. The eight-piece hex-shank listing does not specify a split point in the supplied details. Verify the product specifications if split-point geometry is essential.
