Draper Storm Force® 20V Cordless Combi Drill (Sold Bare)

Drill, drive, and hammer through virtually any material with a single, versatile tool using the Draper Storm Force® CHD20SFN 20V Cordless Combi Drill — a comprehensively specified three-function cordless combi drill from the Draper Storm Force® 20V Power Interchange series that covers drilling, screwdriving, and hammer drilling in one compact, well-equipped package. Sold bare — without battery or charger — the CHD20SFN is the ideal choice for existing Storm Force 20V tool owners who want to add a capable, feature-rich combi drill to their cordless toolkit without investing in a duplicate power system.

The CHD20SFN's three operating functions make it one of the most versatile tools in the Storm Force 20V range. Standard drill mode handles timber, metal, plastic, and a broad range of materials. Screwdriver mode with 22 torque control positions gives precise clutch settings for driving screws of every size — from delicate fine-thread screws into softwood where over-driving is easily done, right through to large structural screws and fixings where maximum torque is needed. Hammer drill mode adds percussion action for efficient drilling through masonry, brick, and blockwork for everyday wall fixing and anchor hole installations up to 13mm.

A two-speed gearbox extends the CHD20SFN's versatility further — low gear delivers maximum torque at reduced speed for heavy-duty screwdriving, driving large fasteners, and demanding drilling applications, while high gear provides faster speeds for lighter driving and drilling tasks where speed is more important than torque. Combined with variable speed trigger control and a no-load speed range of 0–440rpm in first gear and 0–1,650rpm in second, the CHD20SFN can be precisely adapted to virtually any drilling or driving task encountered on site or in the home.

Electronic brake stops the drive instantly on trigger release for accurate screw depth control and improved safety, while a spindle lock holds the chuck stationary for single-handed bit changes. The battery level indicator monitors remaining charge during use, and the integrated LED worklight illuminates the work area ahead of the bit for improved visibility in recesses, cavities, and poorly lit working positions. The 13mm keyless chuck accepts the full range of standard twist drill bits, masonry bits, and driving accessories with fast, tool-free bit changes. Supplied in a carry case, the CHD20SFN is ready for immediate use once paired with a compatible Storm Force 20V battery. Not compatible with Draper Storm Force® 10.8V batteries.

Specifications

FAQ Section

What batteries are compatible with the CHD20SFN?
The CHD20SFN is compatible with all Draper Storm Force® 20V Li-Ion batteries within the 20V Power Interchange series, including the B202LISF 2.0Ah and B20LISF 4.0Ah batteries. It is not compatible with Draper Storm Force® 10.8V batteries. For extended use the 4.0Ah B20LISF is recommended for maximum runtime.

What are the 22 torque control positions for?
The 22 torque control positions allow you to set a precise clutch slip point — the torque level at which the drill's clutch disengages the drive to prevent over-driving or damaging fasteners and materials. Lower numbered settings suit small, delicate screws in softwood; higher settings suit larger screws and harder materials; the drill position bypasses the clutch entirely for maximum torque during drilling. Having 22 positions gives fine, graduated control across the full range of fastener sizes and material types encountered in everyday drilling and driving work.

What is the benefit of a two-speed gearbox?
The two-speed gearbox allows the CHD20SFN to be mechanically optimised for two distinct operating modes. Low gear maximises torque at reduced speed — ideal for heavy-duty screwdriving, driving large or long fasteners, and demanding drilling applications where torque is more important than speed. High gear maximises speed at reduced torque — better suited to faster, lighter driving and drilling tasks. Switching between gears with a physical selector maintains efficiency and extends battery life by matching the mechanical advantage to the task.

How does the CHD20SFN differ from the CID20SF impact driver?
The CHD20SFN is a combi drill — a versatile three-function tool covering drilling, screwdriving, and hammer drilling with a conventional keyless chuck accepting round-shank and hex-shank bits. The CID20SF is a dedicated impact driver with a 1/4" hex quick release collet — designed specifically for high-torque, high-speed screwdriving with hex-shank impact bits, delivering 180Nm versus the CHD20SFN's 50Nm. The CHD20SFN is the more versatile everyday tool for mixed drilling and driving tasks; the CID20SF is the faster, more powerful choice for dedicated screwdriving and fastener removal.

Is the CHD20SFN suitable for hammer drilling into masonry?
Yes, with a maximum masonry drilling capacity of 13mm in hammer mode. The CHD20SFN's hammer function is suited to everyday wall fixing and anchor hole drilling in brick, block, and mortar for standard domestic and trade fixing applications. For larger diameter masonry drilling or sustained heavy-duty hammer work, a dedicated SDS Plus hammer drill such as the Storm Force CSDS20SF is the more appropriate choice.

Why is the CHD20SFN sold bare?
The CHD20SFN is sold without battery or charger to provide the best value for existing Storm Force 20V tool owners who already have compatible batteries and chargers. Batteries and chargers are available separately within the Storm Force 20V range.
